CVE-2023-49102 : Vulnerability Insights and Analysis
Discover the impact of CVE-2023-49102, where NZBGet 21.1 allows authenticated remote code execution. Learn about affected systems, exploitation risks, and mitigation strategies.
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.
