CVE-2026-25607 MEDIUM PATCH This Month

Weak password encoding in STER (all versions before 9.5) exposes stored credentials to local reverse-engineering by any low-privileged user on the system. The root cause (CWE-261) is use of a reversible or insufficiently one-way encoding scheme rather than a cryptographically strong hashing algorithm, enabling an attacker who can observe encoded password data to deduce plaintext values by analyzing patterns across known-value samples. No public exploit code has been identified at time of analysis, and the vulnerability is not listed in the CISA KEV catalog; however, the high confidentiality impact (VC:H in CVSS 4.0) confirms that successful exploitation fully exposes affected credentials. The issue was reported by CERT-PL and fixed by CIOP-PIB in version 9.5.

CVE-2025-11500 HIGH PATCH This Week

An authentication bypass vulnerability in Tinycontrol network devices (tcPDU and LAN Controllers LK3.5, LK3.9, LK4) exposes usernames and encoded passwords for both normal and admin users through unauthenticated HTTP requests to the login page. The vulnerability affects devices running older firmware versions when the secondary authentication mechanism is disabled (default setting), allowing any attacker on the local network to harvest credentials without authentication. With an EPSS score of 0.00043 and no KEV listing, this vulnerability shows low real-world exploitation activity despite its high CVSS score of 8.7.
