CVE-2025-25034

CVE-2025-25034 has been observed exploited in the wild (reported by VulnCheck KEV). EIP tracks 2 public exploits from researchers including Egidio Romano, including a Metasploit module exploits/unix/webapp/sugarcrm_rest_unserialize_exec. A Nuclei detection template is also available.

AI-analyzed exploit summary This Metasploit module exploits a PHP Object Injection vulnerability in SugarCRM CE <= 6.5.23 via unserialize() in the REST API, allowing unauthenticated RCE by writing arbitrary PHP code to the /custom directory.

A PHP object injection vulnerability exists in SugarCRM versions prior to 6.5.24, 6.7.13, 7.5.2.5, 7.6.2.2, and 7.7.1.0 due to improper validation of PHP serialized input in the SugarRestSerialize.php script. The vulnerable code fails to sanitize the rest_data parameter before passing it to the unserialize() function. This allows an unauthenticated attacker to submit crafted serialized data containing malicious object declarations, resulting in arbitrary code execution within the application context. Although SugarCRM released a prior fix in advisory sugarcrm-sa-2016-001, the patch was incomplete and failed to address some vectors. Exploitation evidence was observed by the Shadowserver Foundation on 2024-09-13 UTC.
