CVE-2026-34228 Details
Description
Emlog is an open source website building system. Prior to version 2.6.8, the backend upgrade interface accepts remote SQL and ZIP URLs via GET parameters. The server first downloads and executes the SQL file, then downloads the ZIP file and extracts it directly into the web root directory. This process does not validate a CSRF token. Therefore, an attacker only needs to trick an authenticated administrator into visiting a malicious link to achieve arbitrary SQL execution and arbitrary file write. This issue has been patched in version 2.6.8.
A vulnerability in Emlog's backend upgrade interface prior to version 2.6.8 allows for Cross-Site Request Forgery (CSRF) attacks. The interface accepts remote SQL and ZIP URLs via GET parameters, without validating a CSRF token. This flaw enables an attacker to trick an authenticated administrator into executing arbitrary SQL and writing files to the server. Exploitation involves sending a crafted link that the administrator unwittingly clicks, triggering the malicious actions.
Users are advised to update to Emlog version 2.6.8 or later, where this vulnerability has been patched. Additionally, it is recommended to validate extraction paths for ZIP files before extraction to prevent path traversal vulnerabilities.
