CVE-2015-8765

21
FAUCET Score

CVE-2015-8765 describes a critical remote code execution vulnerability affecting Intel McAfee ePolicy Orchestrator (ePO) versions 4.6.9 and earlier, 5.0.x, 5.1.x before 5.1.3 Hotfix 1106041, and 5.3.x before 5.3.1 Hotfix 1106041. This flaw stems from improper handling of serialized Java objects, leveraging a vulnerability within the Apache Commons Collections library. With a CVSS score of 8.3 (High), this vulnerability allows unauthenticated remote attackers to execute arbitrary code with low attack complexity, potentially leading to significant compromise of confidentiality, integrity, and availability. While no active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion has been observed, the high severity warrants prompt patching.
