Q4What can hackers do? (Privileges/Data)
๐ป **Actions**: Hackers can force the server to access internal/external URLs. ๐ **Data**: Potential theft of sensitive info. ๐ **Impact**: Data modification or executing unauthorized operations via SSRF. ๐ฏ
Q5Is exploitation threshold high? (Auth/Config)
๐ **Auth Required**: YES. The PoC specifies it is **Authenticated**. ๐ **Threshold**: Medium. You need valid credentials first. ๐ถโโ๏ธ Not fully remote unauthenticated, but still dangerous for logged-in users. ๐
Q6Is there a public Exp? (PoC/Wild Exploitation)
๐ข **Public Exp**: YES. Multiple PoCs exist on GitHub. ๐ Links: `cheshireca7/CVE-2022-28117` and `kimstars/POC-CVE-2022-28117`. ๐งช Nuclei templates also available. ๐
Q7How to self-check? (Features/Scanning)
๐ **Check**: Scan for Navigate CMS v2.9.4. ๐ก **Method**: Use Nuclei templates (`CVE-2022-28117.yaml`). ๐งช **Test**: Inject URLs into the `feed` parameter via authenticated sessions. ๐ต๏ธโโ๏ธ

๐ ๏ธ **Fix**: YES. Update to **v2.9.5**. ๐ฅ **Source**: Official blog post confirms the update. ๐ Link: `navigatecms.com/en/blog/development/navigate_cms_update_2_9_5`. โ
Q9What if no patch? (Workaround)
๐ง **No Patch?**: Restrict access to the `feed` parameter. ๐ก๏ธ **Mitigation**: Implement strict URL allowlisting in the `feed_parser`. ๐ซ Block internal IP ranges if possible. ๐
Q10Is it urgent? (Priority Suggestion)
โก **Urgency**: HIGH. ๐ **Published**: April 2022. ๐ **Risk**: SSRF is critical for internal network mapping. ๐จ Patch immediately if running v2.9.4 or older. ๐โโ๏ธ
