CVE-2021-21524

Estado: ModificadaCrítica (9.8)—

Dell SRM versions prior to 4.5.0.1 and Dell SMR versions prior to 4.5.0.1 contain an Untrusted Deserialization Vulnerability. A remote unauthenticated attacker may potentially exploit this vulnerability, leading to arbitrary privileged code execution on the vulnerable application. The severity is Critical as this may lead to system compromise by unauthenticated attackers.
