Information Disclosure

other MEDIUM

Information disclosure occurs when an application unintentionally exposes sensitive data that aids attackers in reconnaissance or directly compromises security.

How It Works

Information disclosure occurs when an application unintentionally exposes sensitive data that aids attackers in reconnaissance or directly compromises security. This happens through multiple channels: verbose error messages that display stack traces revealing internal paths and frameworks, improperly secured debug endpoints left active in production, and misconfigured servers that expose directory listings or version control artifacts like .git folders. APIs often leak excessive data in responses—returning full user objects when only a name is needed, or revealing system internals through metadata fields.

Attackers exploit these exposures systematically. They probe for common sensitive files (.env, config.php, backup archives), trigger error conditions to extract framework details, and analyze response timing or content differences to enumerate valid usernames or resources. Even subtle variations—like "invalid password" versus "user not found"—enable account enumeration. Exposed configuration files frequently contain database credentials, API keys, or internal service URLs that unlock further attack vectors.

The attack flow typically starts with passive reconnaissance: examining HTTP headers, JavaScript bundles, and public endpoints for version information and architecture clues. Active probing follows—testing predictable paths, manipulating parameters to trigger exceptions, and comparing responses across similar requests to identify information leakage patterns.

Impact

  • Credential compromise: Exposed configuration files, hardcoded secrets in source code, or API keys enable direct authentication bypass
  • Attack surface mapping: Stack traces, framework versions, and internal paths help attackers craft targeted exploits for known vulnerabilities
  • Data breach: Direct exposure of user data, payment information, or proprietary business logic through oversharing APIs or accessible backups
  • Privilege escalation pathway: Internal URLs, service discovery information, and architecture details facilitate lateral movement and SSRF attacks
  • Compliance violations: GDPR, PCI-DSS, and HIPAA penalties for exposing regulated data through preventable disclosures

Real-World Examples

A major Git repository exposure affected thousands of websites when .git folders remained accessible on production servers, allowing attackers to reconstruct entire source code histories including deleted commits containing credentials. Tools like GitDumper automated mass exploitation of this misconfiguration.

Cloud storage misconfigurations have repeatedly exposed sensitive data when companies left S3 buckets or Azure Blob containers publicly readable. One incident exposed 150 million voter records because verbose API error messages revealed the storage URL structure, and no authentication was required.

Framework debug modes left enabled in production have caused numerous breaches. Django's DEBUG=True setting exposed complete stack traces with database queries and environment variables, while Laravel's debug pages revealed encryption keys through the APP_KEY variable in environment dumps.

Mitigation

  • Generic error pages: Return uniform error messages to users; log detailed exceptions server-side only
  • Disable debug modes: Enforce production configurations that suppress stack traces, verbose logging, and debug endpoints through deployment automation
  • Access control audits: Restrict or remove development artifacts (.git, backup files, phpinfo()) and internal endpoints before deployment
  • Response minimization: API responses should return only necessary fields; implement allowlists rather than blocklists for data exposure
  • Security headers: Deploy X-Content-Type-Options, remove server version banners, and disable directory indexing
  • Timing consistency: Ensure authentication and validation responses take uniform time regardless of input validity

Local privilege escalation and kernel memory corruption in the Linux kernel's net/sched ETS (Enhanced Transmission Selection) qdisc allows a user with network-configuration capability to corrupt an internal linked list by toggling a scheduling class between DRR and strict modes. When an active DRR class is reconfigured to strict, ets_qdisc_change() fails to remove it from the active list, so switching it back to DRR performs a double list_add, corrupting kernel list pointers. No public exploit has been identified at time of analysis and the EPSS score is very low (0.05%), but the flaw is a classic kernel list-corruption primitive that can escalate to arbitrary write and full compromise.

Kernel memory corruption in the Linux svcrdma transport (server-side NFS-over-RDMA) arises because svc_rdma_copy_inline_range() added the page index (rc_curpage) instead of the byte offset (rc_pageoff) when computing the memcpy destination, so inline payload copies land at the wrong location within the receive pages. On systems exporting NFS over RDMA, a client on the RDMA fabric can drive copies that miscalculate their target offset, leading to out-of-bounds reads/writes in kernel page memory and potential information disclosure or corruption. There is no public exploit identified at time of analysis, EPSS is negligible (0.02%), and the issue is not in CISA KEV, but distro fixes (Ubuntu USN-8177-1) and upstream stable commits are available.

The result is inconsistent delete semantics - files that persist after a delete-on-close or vanish while still in use - with no public exploit identified at time of analysis and a very low EPSS score (0.03%).

Local privilege escalation risk in the Linux kernel's vidtv (Virtual Digital TV) media test driver stems from a double-free and use-after-free condition in vidtv_channel_si_init(), where local pointers are not reset to NULL after ownership of program/service/event list memory is transferred to the PAT/SDT/EIT tables. When vidtv_psi_pmt_create_sec_for_each_pat_entry() fails and control jumps to the free_eit error path, already-freed memory is destroyed a second time. Publicly this is patched upstream and shipped via Ubuntu USN-8096-1, but with EPSS at 0.05% and no public exploit identified at time of analysis, real-world exploitation is unlikely and confined to systems that actually load this virtual test driver.

Out-of-bounds buffer handling in the Linux kernel's ksmbd (in-kernel SMB3 server) Extended Attribute code allows a remote attacker to disclose adjacent kernel memory by sending a crafted SMB2 SET_INFO request. The smb2_set_ea() function validated the request buffer without accounting for the null-terminator byte of the EA name, so the size check under-counted the required length and permitted reads past the intended boundary. No public exploit is identified at time of analysis and EPSS probability is low (0.04%), but a vendor/upstream fix is available and it is not listed in CISA KEV.

Local privilege escalation and memory corruption in the Linux kernel FUSE subsystem's io-uring path allows an unprivileged local user to trigger list corruption and a resulting use-after-free. The flaw stems from a terminated-but-not-committed FUSE io-uring request never being unlinked from the queue's list, leaving a dangling entry that corrupts kernel memory. EPSS is very low (0.03%, 7th percentile) and there is no public exploit identified at time of analysis; a fix has been merged upstream and shipped by distributions such as Ubuntu.

Incorrect access-control enforcement in the Linux kernel's NFSv4 server (nfsd) causes POSIX ACLs supplied during file creation to be silently discarded, so a client that sets an ACL with a named principal ends up with only a default mode-derived ACL instead. This violates RFC 8881 6.4.1.3 and means files intended to carry restrictive or explicitly-granted permissions are instead governed by permissive default mode bits, potentially exposing their contents to unintended principals on the export. There is no public exploit identified at time of analysis, EPSS is very low (0.05%), and it is not on CISA KEV - this is a security-relevant correctness defect rather than an actively exploited threat.

Local privilege-holder-triggered use-after-free in the Linux kernel's mlxsw Spectrum switch driver (drivers/net/ethernet/mellanox/mlxsw) lets a network-admin operation on Nvidia/Mellanox Spectrum ASIC hardware dereference a freed neighbour object during RIF teardown. The driver cached a neighbour pointer without holding a reference, so freeing the neighbour (e.g. while removing a device from a VRF) leaves a dangling pointer that mlxsw_sp_neigh_entry_update() reads, corrupting kernel memory. CVSS is 7.8 (local, low privilege in the automated NVD scoring) but EPSS is only 0.05% (16th percentile) and there is no public exploit or CISA KEV listing - the flaw was found via an internal stress test, not observed attacks.

Local privilege escalation potential arising from a use-after-free in the Linux kernel's mlxsw Spectrum driver (spectrum_mr) allows an attacker with network-administration rights on a Mellanox Spectrum switch to trigger memory corruption during multicast route replacement. A prior fix introduced a dedicated mutex to protect the multicast route list, but one list-entry deletion path during route replace was missed, so the periodic mlxsw_sp_mr_stats_update worker can read a freed route object. EPSS is low (0.05%) and there is no public exploit identified at time of analysis; a vendor patch is available across multiple stable branches.

Denial of service and potential kernel memory disclosure in the Linux kernel's CAIF protocol stack arises because cffrml_receive() subtracts 2 from a packet-derived length field without checking that the value is at least 2 when FCS checking is disabled. An adjacent attacker sending a CAIF frame whose length field is 0 or 1 triggers an integer underflow, leading to memory exhaustion, kernel instability, and possible leakage of uninitialized kernel memory contained in packet padding. There is no public exploit identified at time of analysis, EPSS risk is very low (0.05%), and the flaw is not in CISA KEV.

Out-of-bounds read range miscalculation in the Linux kernel iomap subsystem allows a local attacker who can mount a crafted filesystem image (demonstrated against erofs via syzbot) to trigger a length underflow that returns a read position beyond the folio, leading to information disclosure or memory corruption during buffered reads. The flaw lives in iomap_adjust_read_range(), which incorrectly assumed block-aligned positions and lengths.

Local privilege escalation or kernel memory disclosure in the Linux kernel's amdgpu DRM driver stems from a use-after-free during GPU recovery, where a race between the scheduler timeout callback (drm_sched_job_timedout) and the TDR work queue can free a job structure before amdgpu_device_gpu_recover reads its pasid field. Affected systems are those running vulnerable kernels with AMD GPUs using the amdgpu driver; a local attacker able to submit GPU work and induce a GPU hang could trigger the freed-memory access, as demonstrated by the supplied KASAN slab-use-after-free trace. There is no public exploit identified at time of analysis, and the EPSS score is negligible (0.03%, 7th percentile), consistent with a difficult-to-win kernel race rather than a broadly exploited flaw.

Remote denial of service in the Linux kernel SCSI target (LIO) subsystem allows an initiator to crash a storage server by triggering a NULL-pointer dereference on the command error path. When allocation of the per-command CDB buffer (cmd->t_task_cdb) fails, the pointer is left NULL yet subsequently dereferenced in the 'err' cleanup path, panicking the kernel. No public exploit identified at time of analysis and EPSS is very low (0.05%), consistent with a hard-to-trigger memory-pressure condition rather than a reliably weaponizable flaw.

Refcount underflow in the Linux kernel's net/handshake subsystem lets duplicate cancellation of the same TLS handshake request drop an extra reference on the underlying socket, corrupting its reference count and leaking/freeing the socket structure. The flaw affects kernels using the in-kernel TLS handshake upcall path (notably SUNRPC-over-TLS via tlshd), where a handshake timeout can trigger two cancellation requests - one from xs_reset_transport() and one from xs_tls_handshake_sync() - for a request still present in handshake_rhashtbl. Despite an assigned 9.8 CVSS, the practical impact is a kernel memory-safety fault (crash / potential use-after-free) rather than trivial remote code execution, and there is no public exploit identified at time of analysis; EPSS is very low (0.03%).

Denial of service in the Linux kernel's HFS+ (hfsplus) filesystem driver allows a local user with access to a mounted HFS+ volume to crash the kernel via a reference-counting race in __hfs_bnode_create(). When sync() and link() operations run concurrently, two threads can both attempt to create the same B-tree node; the thread that loses the race reuses the already-hashed node without incrementing its refcount, so a later put trips BUG_ON(!atomic_read(&node->refcnt)) and panics the system.
