Patch Now! baserCMS Vulnerable to Cross-Site Scripting (XSS) Attack (CVE-2024-46995)

2024-10-29

: Websites built with baserCMS versions prior to 5.1.2 are susceptible to a critical Cross-Site Scripting (XSS) vulnerability (CVE-2024-46995). This means attackers can potentially inject malicious scripts into your website, hijacking user sessions, stealing data, or redirecting visitors to harmful sites. Upgrading to baserCMS version 5.1.2 immediately is crucial to address this security risk.

What Undercode Says:

Severity: This vulnerability is classified as Medium Severity according to the Common Vulnerability Scoring System (CVSS). While it doesn’t grant attackers complete control over your system, it can still have significant consequences.
Impact: A successful XSS attack could allow attackers to steal sensitive user data like login credentials or credit card information. They could also use it to deface your website or spread malware to your visitors.
Exploitation: The vulnerability resides in how baserCMS handles certain inputs within HTTP 400 Bad Request responses. This suggests a relatively low attack complexity, meaning attackers with basic skills could potentially exploit it.
Solution: Thankfully, a patch is readily available. Update your baserCMS installation to version 5.1.2 or later as soon as possible.
Prevention: Keeping your CMS software updated with the latest security patches is essential to maintaining a secure website environment. Additionally, consider implementing additional security measures like input validation and content filtering to further mitigate XSS risks.

Additional Considerations:

It’s important to note that the National Vulnerability Database (NVD) hasn’t fully analyzed this vulnerability yet. However, the information available from baserCMS developers suggests a serious security risk.
While the exploitability score is currently low, this could change as attackers develop more sophisticated methods. Don’t wait for an exploit to appear before patching your system.

By taking immediate action and updating to the latest version of baserCMS, you can significantly reduce the risk of falling victim to this XSS vulnerability and protect your website and its visitors.
