Description
SAPCAR allows an attacker logged in with high privileges to override the permissions of the current and parent directories of the user or process extracting the archive, leading to privilege escalation. On successful exploitation, an attacker could modify the critical files by tampering with signed archives without breaking the signature, but it has a low impact on the confidentiality and availability of the system.
Analysis
SAPCAR allows an attacker logged in with high privileges to override the permissions of the current and parent directories of the user or process extracting the archive, leading to privilege escalation. On successful exploitation, an attacker could modify the critical files by tampering with signed archives without breaking the signature, but it has a low impact on the confidentiality and availability of the system.
Technical Context
Privilege escalation allows a low-privileged user or process to gain elevated permissions beyond what was originally authorized.
Remediation
Apply the principle of least privilege. Keep systems patched. Monitor for suspicious privilege changes. Use mandatory access controls (SELinux, AppArmor).
