Ghost CMS XSS Vulnerability
Ghost CMS, a popular content management system, was found to have a cross-site scripting (XSS) vulnerability in its profile image functionality. This vulnerability allowed attackers to inject malicious scripts into profile images, potentially compromising user security. Despite the simplicity of the exploit, it posed a significant risk, especially considering the varying privileged levels within Ghost CMS.
Attack Vector
Attackers could exploit this vulnerability by uploading SVG images containing malicious script tags. These scripts would execute whenever the image was displayed to a victim, leading to potential XSS attacks.
Impact
While Ghost CMS did not immediately patch this vulnerability, it raised concerns due to the potential for privilege escalation. Attackers could target site owners, potentially gaining admin access and compromising the entire system.
ClamAV Vulnerability
ClamAV, an open-source antivirus software, was found to be vulnerable to command injection attacks. By exploiting flaws in the virus event handling mechanism, attackers could execute arbitrary commands on systems running ClamAV.
Exploitation
The vulnerability stemmed from a lack of input sanitization in the handling of file names during virus scanning. Attackers could craft malicious file names containing shell commands, which would be executed when detected by ClamAV.
Impact
This vulnerability could have far-reaching consequences, potentially allowing attackers to take control of systems and compromise sensitive data. Given ClamAV's widespread use, this vulnerability posed a significant threat to cybersecurity.
