Detailsinfo

A vulnerability was found in Cisco Identity Services Engine (Policy Management Software) (affected version not known). It has been classified as problematic. Affected is some unknown functionality of the component Web-based Management Interface. The manipulation with an unknown input leads to a absolute path traversal vulnerability. CWE is classifying the issue as CWE-37. The product accepts input in the form of a slash absolute path ('/absolute/pathname/here') without appropriate validation, which can allow an attacker to traverse the file system to unintended locations or access arbitrary files. This is going to have an impact on confidentiality. CVE summarizes:

Multiple vulnerabilities in the web-based management interface of Cisco Identity Services Engine (ISE) could allow an authenticated, remote attacker to download arbitrary files from the filesystem of an affected device. These vulnerabilities are due to insufficient input validation. An attacker could exploit these vulnerabilities by sending crafted HTTP requests to an affected device. A successful exploit could allow the attacker to download arbitrary files from the underlying filesystem of the affected device.

The weakness was presented 05/18/2023 as cisco-sa-ise-file-dwnld-Srcdnkd2. The advisory is shared for download at sec.cloudapps.cisco.com. This vulnerability is traded as CVE-2023-20087 since 10/27/2022. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1006.

Upgrading eliminates this vulnerability.
