CVE-2025-53882

9.1

SUSE · mailman3

A configuration flaw in the logrotate utility for the mailman3 package on openSUSE allows a local attacker to escalate privileges from the mailman user to root.

Executive summary

A privilege escalation vulnerability in the openSUSE mailman3 logrotate configuration poses a critical risk to system integrity.

Vulnerability

This is a Reliance on Untrusted Inputs in a Security Decision (CWE-807) vulnerability. An attacker with local, low-privileged access can manipulate logrotate operations to achieve root-level code execution.

Business impact

The ability for a low-privileged user to escalate to root access constitutes a complete compromise of the affected host. Given the CVSS score of 9.1, this vulnerability presents a critical threat to server security, potentially allowing an attacker to bypass all system access controls, exfiltrate sensitive data, or install persistent backdoors.

Remediation

Immediate Action: Update the mailman3 package on openSUSE Tumbleweed systems to version 3.3.10-2.1 or later.

Proactive Monitoring: Review system audit logs for unusual process execution patterns or unauthorized attempts to access logrotate configuration files.

Compensating Controls: Restrict local shell access to the smallest possible user base and ensure that file permissions for configuration directories are hardened.

Exploitation status

Public Exploit Available: No (exploit_available: false)

Analyst recommendation

This vulnerability represents a significant security risk for openSUSE administrators. Organizations should prioritize patching the mailman3 package to the recommended version immediately to prevent local privilege escalation.
