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.","provenance":"source","from":"CVE.org"},"summary":{"text":"A deserialization flaw in SugarCRM, affecting versions prior to 6.5.24, 6.7.13, 7.5.2.5, 7.6.2.2 and 7.7.1.0, lies in the SugarRestSerialize.php script, which passes the unsanitised rest_data parameter to unserialize().
