What is CVE-2025-25034?

A PHP object injection vulnerability exists in SugarCRM due to insufficient validation of serialized PHP input in the SugarRestSerialize.php script. The failure to properly sanitize the rest_data parameter before passing it to the unserialize() function allows an unauthenticated attacker to submit crafted serialized data containing malicious object declarations. This results in arbitrary code execution within the application context. Despite a previous advisory addressing security issues, the fixes proved to be incomplete, potentially exposing installations to further risks.

Affected Version(s)

SugarCRM 6.5.0 < 6.5.23

SugarCRM 6.7.0 < 6.7.12

SugarCRM 7.5.0 < 7.5.2.4

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
