CVE-2016-4861

31
FAUCET Score

CVE-2016-4861 describes a critical SQL injection vulnerability (CWE-89) in the Zend Framework before version 1.12.20, specifically affecting the Zend_Db_Select order and group methods. This flaw allows remote attackers to execute arbitrary SQL commands by exploiting the framework's failure to properly sanitize comments from SQL statements before validation. With a CVSS score of 9.8 (CRITICAL), successful exploitation could lead to complete compromise of confidentiality, integrity, and availability of affected systems, including various Fedora and Zend Framework distributions. While no active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion has been observed, the high FAUCET Risk Score of 84/100 indicates a substantial theoretical risk.
