Lifecycle Timeline
8DescriptionCVE.org
A vulnerability was detected in slackero phpwcms up to 1.9.45/1.10.8. The impacted element is an unknown function of the file include/inc_module/mod_feedimport/inc/processing.inc.php of the component Feedimport Module. Performing manipulation of the argument cnt_text results in deserialization. The attack can be initiated remotely. The exploit is now public and may be used. Upgrading to version 1.9.46 and 1.10.9 is sufficient to resolve this issue. The patch is named 41a72eca0baa9d9d0214fec97db2400bc082d2a9. It is recommended to upgrade the affected component.
AnalysisAI
Deserialization vulnerability in phpwcms up to 1.9.45/1.10.8 allows remote attackers with low privileges to execute arbitrary code via the Feedimport Module. Public exploit code exists, and EPSS score is 0.22% (44th percentile), indicating low exploitation likelihood. No active exploitation in CISA KEV.
Technical ContextAI
The vulnerability is a deserialization flaw (CWE-20: Improper Input Validation) in the Feedimport Module of phpwcms, a PHP-based content management system. The affected file is include/inc_module/mod_feedimport/inc/processing.inc.php, where the cnt_text parameter is passed to PHP's unserialize() function without restricting allowed classes. This allows an attacker to inject arbitrary PHP objects, potentially leading to remote code execution via gadget chains. The CPE cpe:2.3:a:phpwcms:phpwcms:*:*:*:*:*:*:*:* indicates all versions are affected.
RemediationAI
Upgrade to phpwcms version 1.9.46 or 1.10.9, which include the fix. The patch commit 41a72eca0baa9d9d0214fec97db2400bc082d2a9 adds the 'allowed_classes' => false parameter to unserialize() calls across multiple files, preventing deserialization of arbitrary classes. No workarounds are documented; upgrading is the recommended action.
