📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
An attacker could steal session cookies, redirect users to phishing sites, or perform actions on behalf of the victim, leading to account compromise or data breaches.
Likely Case
Attackers may use this to steal session tokens or credentials, resulting in unauthorized access to HR data or system functions.
If Mitigated
With input validation and output encoding, the risk is reduced to minimal, preventing script execution and limiting impact to low-severity issues.
🎯 Exploit Status
Exploitation requires tricking a user into clicking a crafted URL, making it straightforward but dependent on social engineering.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://www.incibe.es/en/incibe-cert/notices/aviso/multiple-vulnerabilities-human-resource-management-system
Restart Required: No
Instructions:
Check the vendor advisory for updates; if a patch is released, apply it by updating the software to the fixed version.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement server-side validation to sanitize the 'searccountry' parameter, rejecting or encoding malicious input.
Modify /country.php to use functions like htmlspecialchars() in PHP for output encoding.
Web Application Firewall (WAF) Rule
allDeploy a WAF to block requests containing suspicious scripts in the 'searccountry' parameter.
Configure WAF rules to filter on patterns like <script> or javascript: in URL parameters.
🧯 If You Can't Patch
- Restrict access to the vulnerable endpoint using network controls or authentication to limit exposure.
- Educate users about phishing risks and advise against clicking untrusted links to reduce exploitation likelihood.
🔍 How to Verify
Check if Vulnerable:
Test by accessing /country.php?searccountry=<script>alert('XSS')</script> and check if the script executes in the browser.Check Version:
Check the software version in the admin panel or configuration files; for version 1.0, it is vulnerable.Verify Fix Applied:
After applying fixes, retest the same payload to ensure no script execution occurs and input is properly sanitized.📡 Detection & Monitoring
Log Indicators:
- Look for HTTP requests to /country.php with suspicious parameters containing script tags or encoded payloads.
Network Indicators:
- Monitor for unusual spikes in traffic to /country.php or patterns of malicious URL parameters in network logs.
SIEM Query:
Example: source="web_logs" AND url="/country.php" AND (parameter="searccountry" AND value CONTAINS "<script>" OR "javascript:")
