Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
CVE-2024-6581
Summary
A vulnerability in the discussion image "upload" function of the Lollms application, allows for the uploading of "SVG" files. Due to incomplete filtering in the "sanitize_svg" function, this can lead to Cross-Site Scripting (XSS) vulnerabilities, which in turn pose a risk of Remote Code Execution (RCE). The "sanitize_svg" function only removes script elements and "on*" event attributes, but does not account for other potential vectors for XSS within "SVG" files. This vulnerability can be exploited when authorized users access a malicious "URL" containing the crafted "SVG" file. This issue affects lollms versions 9.5.0 and.after.

Cross-Site Scripting, commonly referred to as XSS, is the most dominant class of vulnerabilities. It allows an attacker to inject malicious code into a pregnable web application and victimize its users. The exploitation of such a weakness can cause severe issues such as account takeover, and sensitive data exfiltration. Because of the prevalence of XSS vulnerabilities and their high rate of exploitation, it has remained in the OWASP top 10 vulnerabilities for years.
