Mongoose

Remote denial of service in Cesanta Mongoose up to version 7.20 allows unauthenticated attackers to trigger an infinite loop via manipulation of TCP option length parameters in the handle_opt function, causing service unavailability. Publicly available exploit code exists. Patch released in version 7.21.

Authorization bypass in Cesanta Mongoose up to version 7.20 allows remote, unauthenticated attackers to bypass TLS certificate signature verification in the P-384 public key handler (mg_tls_verify_cert_signature function in mongoose.c), potentially enabling man-in-the-middle attacks or unauthorized access. The attack is highly complex (CVSS AC:H) but publicly disclosed exploit code exists, with vendor-released patch available in version 7.21.

Stack-based buffer overflow in Cesanta Mongoose mDNS Record Handler (versions up to 7.20) allows remote attackers to trigger memory corruption via malformed mDNS record data in the handle_mdns_record function. The vulnerability requires high attack complexity and network-level access but results in limited confidentiality, integrity, and availability impact. Publicly available exploit code exists; vendor released patched version 7.21 with immediate availability.

Heap-based buffer overflow in Cesanta Mongoose versions up to 7.20 allows unauthenticated remote attackers to compromise confidentiality, integrity, and availability through malicious TLS 1.3 handshake manipulation. The vulnerability resides in mg_tls_recv_cert() function's improper handling of the pubkey argument during certificate processing. Publicly available exploit code exists (CVSS temporal E:P), and vendor-released patch is available in version 7.21. CVSS base score 7.3 reflects network-accessible, low-complexity attack requiring no privileges or user interaction.

A vulnerability was detected in Cesanta Mongoose up to 7.20. This impacts the function mg_chacha20_poly1305_decrypt of the file /src/tls_chacha20.c of the component Poly1305 Authentication Tag Handler. The manipulation results in improper verification of cryptographic signature. The attack may be launched remotely. This attack is characterized by high complexity. The exploitability is said to be difficult. The exploit is now public and may be used. The vendor was contacted early about this di...

A security vulnerability has been detected in Cesanta Mongoose up to 7.20. This affects the function getpeer of the file /src/net_builtin.c of the component TCP Sequence Number Handler. [CVSS 3.7 LOW]

A weakness has been identified in Cesanta Mongoose up to 7.20. The impacted element is the function mg_sendnsreq of the file /src/dns.c of the component DNS Transaction ID Handler. [CVSS 3.7 LOW]

Null pointer dereference in add_ca_certs() in Cesanta Mongoose before 7.2 allows remote attackers to cause a denial of service via TLS initialization where SSL_CTX_get_cert_store() returns NULL. Rated medium severity (CVSS 4.3), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available.

An integer overflow vulnerability exists in the WebSocket component of Mongoose 7.5 thru 7.17. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available.

Mongoose ODM for Node.js before version 8.9.5 contains a search injection vulnerability when using $where filters with populate() match operations. This is an incomplete fix for CVE-2024-53900, allowing attackers to inject arbitrary MongoDB queries through SpEL-like expressions in nested query parameters.
