CVE-2015-7610

22
FAUCET Score

CVE-2015-7610 describes a Cross-Site Request Forgery (CSRF) vulnerability in the login form of Zimbra Collaboration Suite (ZCS) versions prior to 8.6.0 Patch 10, 8.7.x before 8.7.11 Patch 2, and 8.8.x before 8.8.8 Patch 1. This vulnerability, which allows remote attackers to hijack user authentication due to the absence of a CSRF token, carries a high CVSS v3.0 score of 8.8, indicating a network-based attack with low complexity and high impact on confidentiality, integrity, and availability. While the EPSS score suggests a low probability of exploitation, there is no known public exploit code (Metasploit, Nuclei, ExploitDB), and it is not listed on the CISA KEV catalog, nor does it show significant community discussion or media coverage.
