CVE-2021-20271

CVE-2021-20271 describes a flaw in RPM's signature verification process, affecting products like fedoraproject, Red Hat, and StarWind Software. An attacker could exploit this by tricking a user into installing a maliciously modified, yet seemingly valid, RPM package. This high-severity vulnerability (CVSS 7.0) carries significant risks to data integrity, confidentiality, and system availability, requiring user interaction and high attack complexity. While there is no known active exploitation or public exploit code (Metasploit, Nuclei, ExploitDB), community discussion highlights the importance of enabling GPG checks for RPM repositories.
