Renaud Bastide Christophe Wolfhugel · Sympa · CVE-2020-26880
**Name of the Vulnerable Software and Affected Versions**
Sympa versions through 6.2.57b.2
**Description**
The issue allows a local privilege escalation from the sympa user account to full root access. This is achieved by modifying the `sympa.conf` configuration file, which is owned by sympa, and then parsing it through the setuid `sympa newaliases-wrapper` executable.
**Recommendations**
For versions through 6.2.57b.2, consider restricting access to the `sympa newaliases-wrapper` executable as a temporary workaround until a patch is available. Additionally, limit modifications to the `sympa.conf` configuration file to minimize the risk of exploitation.
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
