How the Mentioned CVE Works:
CVE-2025-22760 is a critical vulnerability in CodeBard Help Desk, versions up to 1.1.2, caused by improper neutralization of user input during web page generation. This flaw allows attackers to inject malicious scripts into web pages viewed by other users, leading to Reflected Cross-site Scripting (XSS). When a user interacts with a crafted URL or input, the injected script executes in their browser, potentially stealing sensitive information, hijacking sessions, or performing actions on behalf of the user. The vulnerability arises due to insufficient validation and sanitization of user-supplied data before rendering it in the web page.
DailyCVE Form:
Platform: CodeBard Help Desk
Version: 1.1.2 and earlier
Vulnerability: Reflected XSS
Severity: Critical
Date: 01/15/2025
What Undercode Say:
Exploitation:
1. Craft Malicious URL:
Attackers create a URL with a malicious script payload, e.g.,
`https://example.com/search?query=`
2. Send to Victim:
The attacker tricks the victim into clicking the link via phishing or social engineering.
3. Script Execution:
The victim’s browser executes the script, leading to data theft or session hijacking.
Protection:
1. Input Sanitization:
Use libraries like DOMPurify to sanitize user inputs.
const cleanInput = DOMPurify.sanitize(userInput);
2. Content Security Policy (CSP):
Implement CSP headers to restrict script execution.
Content-Security-Policy: default-src 'self'; script-src 'self';
3. Output Encoding:
Encode user inputs before rendering them in HTML.
function encodeHTML(str) {
return str.replace(/&/g, '&').replace(/</g, '<').replace(/>/g, '>');
}
4. Framework Protections:
Use modern frameworks like React or Angular that automatically escape user inputs.
Commands:
1. Check for Vulnerable Versions:
grep -r "CodeBard Help Desk" /var/www/html/
2. Update to Patched Version:
wget https://example.com/CodeBard-Help-Desk-1.1.3.zip unzip CodeBard-Help-Desk-1.1.3.zip -d /var/www/html/
