CVE-2023-53892 is a high-severity remote code execution vulnerability in Blackcat CMS version 1.4. Authenticated administrators can exploit this flaw via the jquery plugin manager by uploading a malicious zip file containing PHP shell scripts. The vulnerability allows execution of arbitrary system commands by accessing the uploaded PHP file with a crafted 'code' parameter. No user interaction or additional authentication beyond admin privileges is required. This vulnerability poses a significant risk to the confidentiality, integrity, and availability of affected systems. Although no known exploits are currently reported in the wild, the ease of exploitation and high impact make timely remediation critical. European organizations using Blackcat CMS 1.4 should prioritize patching or mitigating this vulnerability to prevent potential compromise. Countries with higher adoption of Blackcat CMS or critical infrastructure relying on it are at greater risk.

CVE-2023-53891 is a stored cross-site scripting (XSS) vulnerability in Blackcat CMS version 1.4 that allows authenticated users to inject malicious JavaScript into page content. When other users view the compromised page, the injected scripts execute, potentially leading to session hijacking, credential theft, or unauthorized actions. The vulnerability requires authentication and some user interaction, and it has a medium severity CVSS score of 5.1. No known exploits are currently reported in the wild. European organizations using Blackcat CMS 1.4, especially those with multiple authenticated users managing content, are at risk. Mitigation involves applying patches once available, restricting user permissions, implementing input sanitization, and monitoring CMS activity. Countries with higher adoption of Blackcat CMS or significant web content management needs, such as Germany, France, and the UK, may be more affected.
