Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: Path Traversal in `move-file` function via `newPath` parameter.โฆ
๐ก๏ธ **Root Cause**: Improper validation of the `newPath` argument in the `move-file` function. <br>๐ **CWE**: Path Traversal (CWE-22). The system fails to sanitize directory traversal sequences. ๐
Q3Who is affected? (Versions/Components)
๐ข **Vendor**: South River Technologies. <br>๐ฆ **Product**: TitanFTP NextGen (SFTP/FTP Server). <br>๐ **Affected Versions**: v1.94.1205 and earlier. โ ๏ธ
Q4What can hackers do? (Privileges/Data)
๐ต๏ธ **Attacker Actions**: Upload a file, then use the vulnerable `move-file` function to relocate it anywhere on the filesystem.โฆ
๐ **Threshold**: **Medium**. Requires **Authentication**. <br>โ๏ธ **Config**: The attacker must be a valid user to access the FTP/SFTP service and trigger the move operation. ๐ช
Q6Is there a public Exp? (PoC/Wild Exploitation)
๐ **Public Exploit**: Yes. <br>๐ **PoC Available**: Nuclei templates and PacketStorm security advisories exist. <br>๐ฅ **Status**: Known exploitation techniques are documented online. ๐ข
Q7How to self-check? (Features/Scanning)
๐ **Self-Check**: Scan for TitanFTP NextGen services. <br>๐งช **Test**: Attempt to upload a file, then send a crafted `move-file` request with `../` in the `newPath` parameter.โฆ
๐ฉน **Official Fix**: Check vendor release notes for updates post-1.94.1205. <br>๐ **Mitigation**: Apply the latest patch from South River Technologies if available. Ensure `newPath` is strictly validated. โ
Q9What if no patch? (Workaround)
๐ง **No Patch?**: Restrict FTP/SFTP user permissions. <br>๐ **Network**: Block external access to FTP ports if not needed. <br>๐๏ธ **Monitor**: Log all file move operations for suspicious directory traversal attempts. ๐
Q10Is it urgent? (Priority Suggestion)
๐จ **Urgency**: **High**. <br>๐ **Priority**: Critical for any TitanFTP users. <br>โณ **Action**: Patch immediately or apply strict network controls. The vulnerability allows significant system impact. โก
