A vulnerability was found in Cisco TelePresence Collaboration Endpoint (Unified Communication Software) (version now known) and classified as critical. This issue affects some unknown processing of the component CLI. The manipulation with an unknown input leads to a privileges management vulnerability. Using CWE to declare the problem leads to CWE-269. The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. Impacted is integrity, and availability. The summary by CVE is:

Multiple vulnerabilities in the CLI of Cisco TelePresence Collaboration Endpoint (CE) Software could allow an authenticated, local attacker to overwrite arbitrary files. The vulnerabilities are due to insufficient permission enforcement. An attacker could exploit these vulnerabilities by authenticating as the remote support user and submitting malicious input to specific commands. A successful exploit could allow the attacker to overwrite arbitrary files on the underlying filesystem. The attacker has no control over the contents of the data written to the file. Overwriting a critical file could cause the device to crash, resulting in a denial of service condition (DoS).

The weakness was disclosed 10/16/2019 as cisco-sa-20191016-tele-ce-file as confirmed advisory (Website). It is possible to read the advisory at tools.cisco.com. The identification of this vulnerability is CVE-2019-15273 since 08/20/2019. Attacking locally is a requirement. Required for exploitation is a simple authentication. The technical details are unknown and an exploit is not publicly available. The attack technique deployed by this issue is T1068 according to MITRE ATT&CK.
