Kerentanan Improper Privilege Management pada squid-cache squid. Skor CVSS 3.1 4.5 (Medium) menurut NVD.

Deskripsi (NVD)

An issue was discovered in Squid through 4.7. When Squid is run as root, it spawns its child processes as a lesser user, by default the user nobody. This is done via the leave_suid call. leave_suid leaves the Saved UID as 0. This makes it trivial for an attacker who has compromised the child process to escalate their privileges back to root.
