CVE-2026-35083: CWE-121 Stack-based Buffer Overflow in MBS Single-A
A remote attacker with user privileges can exploit a stack buffer overflow to gain full system access as root.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-35083) involves a stack-based buffer overflow (CWE-121) in the MBS Single-A product. A remote attacker with user-level privileges can exploit this flaw to escalate privileges and gain full system access as root. The CVSS 4.0 vector indicates network attack vector, low attack complexity, no privileges required beyond user level, no user interaction, and high impact on confidentiality, integrity, and availability. No patch or vendor advisory is currently available to confirm remediation status.
Potential Impact
Successful exploitation allows a remote attacker with user privileges to execute a stack-based buffer overflow, resulting in full system compromise with root privileges. This can lead to complete control over the affected system, including unauthorized data access, modification, and disruption of service.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict user-level access and monitor for suspicious activity related to this vulnerability. Avoid exposing the vulnerable service to untrusted networks if possible.
