Detailsinfo

A vulnerability, which was classified as critical, was found in A10 AX Loadbalancer up to 2.6.1-GR1-P5/2.7.0. Affected is some unknown functionality of the file /xml/downloads. The manipulation of the argument filename with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as 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. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

A path traversal vulnerability exists in A10 Networks AX Loadbalancer versions 2.6.1-GR1-P5, 2.7.0, and earlier. The vulnerability resides in the handling of the filename parameter in the /xml/downloads endpoint, which fails to properly sanitize user input. An unauthenticated attacker can exploit this flaw by sending crafted HTTP requests containing directory traversal sequences to read arbitrary files outside the intended directory. The files returned by the vulnerable endpoint are deleted from the system after retrieval. This can lead to unauthorized disclosure of sensitive information such as SSL certificates and private keys, as well as unintended file deletion.
