CVE-2021-33553

60
FAUCET Score

CVE-2021-33553 describes a critical command injection vulnerability affecting multiple camera devices from vendors like UDP Technology and Geutebrück, allowing remote attackers to execute arbitrary code. With a CVSS score of 7.2 (HIGH) and an EPSS score indicating high exploitability, this flaw can lead to complete compromise of affected systems due to its network-based attack vector and high impact on confidentiality, integrity, and availability. While not on CISA's KEV catalog, a Metasploit module exists, and its mention in media coverage regarding Mirai DDoS malware suggests potential for active exploitation in the wild, warranting immediate patching.
