Detailsinfo

A vulnerability was found in Microweber up to 2.0.20. It has been declared as problematic. This vulnerability affects the function normalize_path of the component Static File Controller. The manipulation of the argument path with an unknown input leads to a path traversal vulnerability. The CWE definition for the vulnerability is CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. As an impact it is known to affect confidentiality. CVE summarizes:

Microweber CMS through 2.0.20 contains a path traversal vulnerability in the static file controller that allows unauthenticated remote attackers to read arbitrary files by supplying directory traversal sequences in the path query parameter. Attackers can send a single unauthenticated HTTP GET request exploiting the failure of normalize_path() to strip traversal sequences, disclosing sensitive files such as environment configuration files containing credentials and system files.

The advisory is available at github.com. This vulnerability was named CVE-2026-65694 since 07/22/2026. The exploitation appears to be easy. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. Technical details are known, but there is no available exploit. The structure of the vulnerability defines a possible price range of USD $0-$5k at the moment (estimation calculated on 07/23/2026). This vulnerability is assigned to T1006 by the MITRE ATT&CK project.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
