The WikiManager REST API vulnerability (CVE-2025-XXXX) allows any user to create wikis, potentially escalating privileges to administrator level. This flaw exists in affected versions of the REST module, specifically versions >= 5.4-rc-1 and < 15.10.15, >= 16.0.0-rc-1 and < 16.4.6, and >= 16.5.0-rc-1 and < 16.10.0. The issue arises due to improper access controls in the API, enabling unauthorized users to create wikis and gain administrative rights. This can lead to further exploitation, such as data manipulation or system compromise. The vulnerability is critical as it allows privilege escalation without requiring advanced technical skills. Patched versions (15.10.15, 16.4.6, and 16.10.0) address this issue by enforcing proper access controls.
DailyCVE Form:
Platform: WikiManager REST API
Version: 5.4-rc-1 to 16.10.0
Vulnerability: Privilege Escalation
Severity: Critical
Date: Mar 19, 2025
What Undercode Say:
Exploitation:
1. Exploit Code:
curl -X POST http://<target>/rest/wikimanager/create -d '{"name":"exploit_wiki","admin":"true"}'
This command exploits the API to create a wiki with admin privileges.
2. Privilege Escalation:
Once the wiki is created, the attacker can log in as an admin and execute further attacks.
3. Impact Analysis:
- Unauthorized administrative access.
- Potential data breaches or system compromise.
Protection:
1. Patch Installation:
Upgrade to patched versions (15.10.15, 16.4.6, or 16.10.0).
sudo apt-get update && sudo apt-get install xwiki-rest=16.10.0
2. Access Control:
Restrict API access to trusted users only.
iptables -A INPUT -p tcp --dport 8080 -s <trusted_ip> -j ACCEPT
3. Monitoring:
Use logging to detect unauthorized API calls.
tail -f /var/log/xwiki/rest_api.log
4. Disable Unused Modules:
If the REST API is not required, disable it.
rm -rf /path/to/rest/module
5. Security Audits:
Regularly audit user roles and permissions.
grep "admin" /path/to/user_roles.csv
6. Network Segmentation:
Isolate the REST API server from critical systems.
vlan create 10
7. Incident Response:
If exploited, revoke admin access and investigate logs.
grep "create" /var/log/xwiki/rest_api.log
8. User Education:
Train users to recognize phishing or social engineering attempts.
9. Backup Strategy:
Regularly back up wiki data to mitigate ransomware risks.
tar -czvf wiki_backup_$(date +%F).tar.gz /path/to/wiki/data
10. Vulnerability Scanning:
Use tools like Nessus or OpenVAS to detect unpatched systems.
openvas-cli --target=<target_ip> --scan
By following these steps, organizations can mitigate the risks associated with CVE-2025-XXXX and ensure the security of their WikiManager REST API.
