CVE-2017-4990

31
FAUCET Score

CVE-2017-4990 describes a critical arbitrary code execution vulnerability in multiple versions of EMC Avamar Server Software. An unauthenticated attacker can exploit a file upload feature on the system maintenance page to upload a malicious file to any directory, leading to complete compromise of the Avamar Server. This vulnerability carries a CVSS score of 9.8 (Critical) due to its network-based attack vector, low attack complexity, and high impact on confidentiality, integrity, and availability. While no public exploit intelligence (Metasploit, Nuclei, ExploitDB) or active exploitation (KEV) is reported, and community discussion is minimal, the severe nature of this flaw warrants immediate patching.
