CVE-2025-52985 is a "Use of Incorrect Operator" vulnerability in Juniper Networks Junos OS Evolved, specifically affecting the Routing Engine firewall. This flaw allows an unauthenticated, network-based attacker to bypass security restrictions when a firewall filter on lo0 or re:mgmt interfaces references a prefix list with more than 10 entries, causing packets to be unfiltered. The vulnerability has a CVSS score of 5.3 (Medium), indicating a low attack complexity and no user interaction required, potentially leading to a loss of integrity (bypassed filtering) but no confidentiality or availability impact. It affects various Junos OS Evolved versions, including 23.2R2-S3-EVO, 23.4R2-S3-EVO, 24.2R2-EVO, and 24.4-EVO. Currently, there is no evidence of active exploitation, and no public exploit code (Metasploit, Nuclei, ExploitDB) is available. Community discussion and media coverage for this CVE are minimal, which is typical for the majority of reported vulnerabilities.
