CVE-2023-49102

Status: ModifiedHigh (8.8)—

NZBGet 21.1 allows authenticated remote code execution because the unarchive programs (7za and unrar) preserve executable file permissions. An attacker with the Control capability can execute a file by setting the value of SevenZipCommand or UnrarCmd. NOTE: This vulnerability only affects products that are no longer supported by the maintainer.

CVSS
