CVE-2026-65117 Sep 22, 14:10 HIGH This Week

Hard-coded credentials in NVIDIA Infrastructure Controller for Linux (versions 0 through 1.9) let an unauthenticated attacker who can reach the device from an adjacent network segment log in with embedded, static credentials, resulting in high confidentiality, integrity, and availability impact (CVSS 3.1 8.8, AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H). Because the password is static across installations and recoverable by anyone who can inspect the binary or firmware image, exploitation requires no user interaction and no prior authentication, but it does require the attacker to reside on the same broadcast or management network segment rather than the open internet. No public exploit code has been identified at time of analysis, there is no CISA KEV listing, and EPSS is low at 0.23% (14th percentile), with CISA SSVC rating exploitation as "none" and the attack as not automatable.

CVE-2026-71809 Sep 09, 00:00 HIGH This Week

Authentication bypass in Siam Ordering (siam-server) 1.0.0 lets remote attackers log in as any user, merchant, or administrator by supplying a hardcoded master verification code that ships with the server. The flaw is rooted in a hardcoded credential (CWE-259) rather than a memory-safety or logic error, so every deployment of version 1.0.0 that exposes the verification endpoint is potentially affected, with full confidentiality, integrity, and availability impact once a session is obtained. No public exploit code has been identified and the EPSS score is low (0.24%, 16th percentile), but the issue is trivially severe if the code value is known or recoverable, and no vendor-released patch was identified in the available data.

Unauthenticated device login in XING Inc.'s CPTrans-ME-X AV signal-transport appliance is possible via a hard-coded password (CWE-259): anyone who knows the built-in credential can authenticate over the network and gain full control of the device. The flaw was coordinated through JPCERT/CC (JVN JVN32505330) and carries a CVSS 4.0 base score of 9.3 with high confidentiality, integrity, and availability impact. No public exploit has been identified at time of analysis, and the product is niche, but the fixed credential makes exploitation trivial once the value is known.

CVE-2026-23933 Aug 18, 12:18 HIGH This Week

Session cookie forgery in Zabbix 7.4 is possible because the cryptographic key used to sign Frontend sessions is erroneously written to the database seed, making it readable by anyone with adjacent database access. The vendor-confirmed exploitation path is narrowly scoped: only deployments running both SAML authentication and guest users simultaneously are at known risk, where the extracted key can be used to forge valid session cookies and achieve unauthorized frontend access. No public exploit code or active exploitation (CISA KEV) has been identified at time of analysis, and the vendor explicitly states no known impact for deployments outside the SAML-plus-guest-user configuration.

Hard-coded TR-069 remote management credentials in LB-LINK X-PRO firmware 1.0.22-20231206 allow network-accessible unauthenticated attackers to authenticate to the device's CWMP interface via static credentials embedded in /etc/config/easycwmp. A public proof-of-concept exploit has been released, effectively eliminating the primary barrier to exploitation. The vendor was unresponsive to coordinated disclosure, and no patch has been issued; no public exploit identified at time of analysis as confirmed active exploitation (CISA KEV listing absent), though publicly available exploit code exists.

CVE-2026-19900 Aug 15, 17:16 HIGH POC This Week

Hard-coded credentials embedded in the /etc/shadow file of the LB-LINK X-PRO wireless router (firmware 1.0.22-20231206) allow remote attackers who obtain those static credentials to authenticate to the device's management interface without any privilege requirement. The affected product is also marketed as the B-Link AC1200 X-PRO (model AC6). A public proof-of-concept has been published, effectively neutralizing the high attack complexity barrier by making the hardcoded password discoverable; no vendor patch exists because the vendor did not respond to disclosure, leaving all deployed units permanently vulnerable to authentication bypass and full device compromise.

Hard-coded SSH credentials embedded in Tenda CH, CP, and TX3 camera firmware across versions V21.x through V27.x expose all affected devices to remote authentication bypass, granting shell-level access to any attacker who obtains the static password. A GitHub-published proof-of-concept documents the exact credential and exploitation steps, significantly collapsing the barrier imposed by the CVSS 4.0 AC:H rating. No vendor-released patch has been identified at time of analysis, and no CISA KEV listing has been issued, though the public exploit makes this a credible near-term threat for network-exposed devices.

Hardcoded static credentials in Cisco Secure Firewall Management Center (FMC) Software allow an unauthenticated remote attacker to log in to the web interface using a built-in low-privileged account and access sensitive data. The flaw affects an extensive range of FMC versions from 7.0.0 through 10.0.1 and is rooted in CWE-259 (Use of Hard-coded Password). Cisco has self-elevated the Security Impact Rating to High - despite a CVSS 5.3 Medium score - explicitly because this credential foothold can be chained with other FMC vulnerabilities to escalate privileges, making the real-world risk materially higher than the base score implies. No public exploit or CISA KEV listing has been confirmed at time of analysis.

Hardcoded root credentials in T3 Technology CPE devices (models T625Pro v1.0.07, T6825G v1.0.03, and T7281 v1.0.03) allow remote unauthenticated attackers to gain full root-level control via the built-in 'superadmin' account. The CVSS 9.8 rating reflects network-reachable, no-interaction exploitation with total impact to confidentiality, integrity, and availability, and SSVC marks the issue as automatable with total technical impact. No public exploit identified at time of analysis, and EPSS remains very low (0.02%) despite the severity, suggesting limited current scanning activity.
