CVE-2018-10852 (GCVE-0-2018-10852)

Vulnerability from cvelistv5 – Published: 2018-06-26 14:00 – Updated: 2024-08-05 07:46

Summary

The UNIX pipe which sudo uses to contact SSSD and read the available sudo rules from SSSD has too wide permissions, which means that anyone who can send a message using the same raw protocol that sudo and SSSD use can read the sudo rules available for any user. This affects versions of SSSD before 1.16.3.

Severity

3.8 (Low)
