Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: Path Traversal in `state_token` parameter. <br>๐ฅ **Consequences**: Denial of Service (DoS) or Arbitrary File Operations. Critical integrity/availability impact.
Q2Root Cause? (CWE/Flaw)
๐ก๏ธ **CWE**: CWE-22 (Path Traversal). <br>๐ **Flaw**: Improper handling of user-supplied input in the `state_token` field, allowing directory traversal sequences.
Q3Who is affected? (Versions/Components)
๐ฆ **Affected**: Mesop (Python Web UI Framework). <br>๐ **Versions**: v1.2.2 and earlier. <br>๐ค **Vendor**: mesop-dev.
Q4What can hackers do? (Privileges/Data)
๐ต๏ธ **Capabilities**: Read/Write arbitrary files on the server. <br>๐ **Privileges**: High (CVSS A:H, I:H, C:H). Can potentially compromise system stability or leak sensitive data.
Q5Is exploitation threshold high? (Auth/Config)
๐ **Threshold**: LOW. <br>๐ **Details**: CVSS indicates `AV:N` (Network), `AC:L` (Low Complexity), `PR:N` (No Privileges Required), `UI:N` (No User Interaction). Easy to exploit remotely.
Q6Is there a public Exp? (PoC/Wild Exploitation)
๐ซ **Public Exploit**: No PoCs listed in data. <br>โ ๏ธ **Risk**: Despite no public code, the low complexity and network vector make theoretical exploitation straightforward for attackers.
Q7How to self-check? (Features/Scanning)
๐ **Check**: Scan for Mesop v1.2.2 or older. <br>๐ก **Features**: Look for `state_token` parameter in HTTP requests. Use SAST/DAST tools to detect path traversal patterns in Python web apps.
Q8Is it fixed officially? (Patch/Mitigation)
โ **Fixed**: Yes. <br>๐ฆ **Patch**: Upgrade to **v1.2.3** or later. <br>๐ **Ref**: GitHub Release v1.2.3 & Commit c6b382f.
Q9What if no patch? (Workaround)
๐ก๏ธ **Workaround**: If upgrading is impossible, implement strict input validation/sanitization for `state_token` to reject `../` sequences. Restrict file access permissions.
