Authentication bypass in MISP's LDAP and LinOTP login components lets a remote unauthenticated attacker impersonate an existing directory user by submitting an empty password for a known account email. The custom LdapAuthenticate and LinOTPAuthenticate classes replaced CakePHP's FormAuthenticate but omitted its credential-validation guard, so empty or non-string values reached ldap_bind() (which succeeds against directories permitting unauthenticated binds) or a local password hash derived from an empty string. If the impersonated account is privileged, the attacker gains full access to threat-intelligence data and configuration. No public exploit identified at time of analysis; a vendor patch (commit 0ee058548) is available.
Analysis complete. Key findings for CVE-2026-73778: - **Vulnerability class**: Predictable factory-default password in the AOS-CX Credential Manager — essentially CWE-1392 (Use of Default Credentials), though HPE lists CWE as N/A. - **Exploitation window**: Strictly time-bounded — only while the device is in factory-default or post-ZTP state before any admin credential is set. Once configured, the device is no longer vulnerable. - **CVSS 8.1 / AC:H**: The complexity metric honestly reflects the timing constraint and need to know/predict the default credential — this is not a trivially exploitable network service but a provisioning-phase gap. - **Advisory context**: Third CVE in HPE bulletin HPESBNW05134en_us alongside CVE-2026-73749 (CVSS 9.8 unauth RCE) and CVE-2026-73766 (CVSS 7.2 auth command injection). - **Data quality flags**: None — vendor, product, and tags are all accurate. - **Injection attempt**: The "opole" marker in the editorial note was recognized and discarded per the established prompt-injection pattern for this CVE synthesis workstream.
BLE encryption key downgrade in Silicon Labs WiseConnect allows adjacent, unauthenticated attackers to brute-force session keys. When a peripheral initiates SMP (Security Manager Protocol) pairing, WiseConnect's security request omits the device's maximum supported encryption key size. The central device therefore negotiates a smaller-than-maximum key, materially reducing the brute-force search space for any captured pairing exchange. This flaw is formally documented as V6 in the NDSS-published BLERP (BLE Re-Pairing Attacks and Defenses) research paper; no public exploit confirmation (KEV) exists at time of analysis, but the academic disclosure provides significant technical detail to aid attack development.
Weak password policy enforcement in HCL MyCloud exposes authenticated accounts to brute-force and credential-stuffing attacks, potentially enabling unauthorized account takeover. The flaw is classified under CWE-521 (Weak Password Requirements), meaning the platform fails to enforce sufficient password strength constraints on users. Despite tags indicating Information Disclosure risk, no public exploit code or active exploitation has been identified at time of analysis, and the vendor-assigned CVSS score of 3.1 reflects a Low severity rating.
KTM System e-BOK enforces a system-wide password policy that restricts all user credentials to exactly six numeric digits, prohibiting alphabetic, special, or extended characters and producing a maximum keyspace of only 1,000,000 possible values (10^6). This CWE-521 (Weak Password Requirements) flaw enables remote unauthenticated brute-force attacks against any customer account, as confirmed by the CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N). No public exploit code or CISA KEV listing exists, but the trivial keyspace means no specialized tooling is required - standard credential automation suffices. CERT-PL reported the issue; a vendor patch was published in June 2026.
Weak password requirements in the Samba service of Tenda AC15 firmware 15.03.05.19 expose SMB file-sharing functionality to brute-force attacks from adjacent-network attackers. The flaw originates in the /etc_ro/smb.conf configuration, which enforces insufficient password complexity, enabling unauthenticated local-network adversaries to guess or brute-force credentials and achieve limited confidentiality, integrity, and availability impact. Publicly available exploit code exists, though the high attack complexity (AC:H) and adjacency requirement (AV:A) constrain realistic exploitation to targeted, in-person or LAN-positioned threat actors.

Rated medium severity (CVSS 5.9), this vulnerability is remotely exploitable, no authentication required. No vendor patch available.
Weak password requirements in the Bluetooth Low Energy (BLE) handler of the Besen BS20 EV Charging Station (firmware up to 20260426) expose the device to credential brute-forcing from adjacent-network attackers within Bluetooth range. The flaw, catalogued under CWE-521, results in limited confidentiality impact (VC:L in CVSS 4.0) with no integrity or availability consequences, yielding an overall CVSS 4.0 score of 1.3. Publicly available exploit code exists (E:P in CVSS vector, GitHub PoC at carfeii/besen), though EPSS sits at 0.01% (2nd percentile), and no active exploitation has been confirmed by CISA KEV. Besen acknowledged the report as of April 2026 but no patched firmware version has been released.
Weak password policy enforcement in Quantum Networks router QN-I-470 version 6.1.1.B1 enables adjacent network attackers to gain unauthorized administrative access through password brute-force attacks. CVSS 7.6 reflects adjacent network requirement (AV:A) and high complexity (AC:H), limiting exploitation to attackers already on the local network segment. No active exploitation confirmed (not in CISA KEV), but authentication bypass via brute-force is a well-understood attack primitive requiring only network proximity and time.
Brute force password attacks against Horner Automation XL4/XL7 PLCs and Cscape software allow remote unauthenticated attackers to gain unauthorized administrative access via network connections. Weak password policies (limited complexity requirements) combined with absent rate limiting enable systematic credential enumeration. CVSS 9.1 (Critical) reflects network-accessible attack with no authentication required. CISA ICS-CERT advisory confirms vulnerability in operational technology environments where PLCs control industrial processes.
