CVE-2026-12502: CWE-269 Improper privilege management in Loytec LIP-ME20xC
CVE-2026-12502 is a high-severity vulnerability in Loytec LIP-ME20xC devices and related products up to version 8.4.16 on LINX-A64. It involves improper privilege management in the /usr/bin/ltsudo binary, allowing an attacker with superadmin group privileges to reset the password of any LARM user, including critical service accounts such as larmapp, via the set-passwd subcommand. This vulnerability could enable unauthorized privilege escalation within affected systems.
AI Analysis
Technical Summary
This vulnerability (CWE-269) affects the /usr/bin/ltsudo component in Loytec LIP-ME201C and related products running up to version 8.4.16 on LINX-A64. A user with superadmin group privileges can exploit improper privilege management to reset passwords of any LARM user account, including the larmapp service account, by using the set-passwd subcommand. The CVSS 4.0 base score is 8.4, indicating high severity, with attack vector local, low attack complexity, and no user interaction required. The vulnerability does not affect cloud services and no official patch or remediation level has been published as of the advisory date.
Potential Impact
An attacker who already has superadmin group privileges can reset passwords for any LARM user account, including service accounts, potentially leading to unauthorized access or privilege escalation within the affected device environment. This could compromise system integrity and control over the affected Loytec devices.
Mitigation Recommendations
No official patch or remediation has been published yet. Since the vulnerability requires superadmin group access, restricting and monitoring membership of this group is recommended as a temporary mitigation. Check the vendor advisory regularly for updates on patches or official fixes.
