A vulnerability in the web UI of Cisco IOS XE Software could allow an authenticated, remote attacker to perform an injection attack against an affected device. This vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by sending crafted input to the web UI. A successful exploit could allow the attacker to execute arbitrary Cisco IOS XE Software CLI commands with level 15 privileges. Note: This vulnerability is exploitable only if the attacker obtains the credentials for a Lobby Ambassador account. This account is not configured by default.
The vulnerability has been assigned a CVSS score of 8.8, categorizing it as high severity. The implications of this vulnerability are significant, as it can lead to unauthorized access and control over affected devices. Organizations utilizing Cisco IOS XE should prioritize remediation to prevent potential exploitation.
Risk to organizations includes potential unauthorized command execution, system compromise, and data integrity issues. Given the high vulnerability score and the nature of the attack vector, organizations should prioritize patching immediately.
As of now, there are no known exploits or public proof of concepts available for this vulnerability. However, the threat landscape remains dynamic, and organizations are encouraged to monitor for any updates regarding this vulnerability.
Vulnerability Details
The vulnerability in question allows an authenticated remote attacker to perform an injection attack due to insufficient input validation within the web UI of Cisco IOS XE Software. The affected versions include 16.12.4, 16.12.5, 17.3.1, among others. Cisco has provided a detailed advisory regarding this vulnerability, which was published on September 27, 2023.
Technical Analysis
The root cause of this vulnerability is the insufficient input validation mechanism present in the web UI of the Cisco IOS XE Software. The attack vector is through network access, leveraging low privileges of the Lobby Ambassador account. This means that while the attacker needs some level of access, they do not need full administrative privileges to exploit this vulnerability. The impact on confidentiality, integrity, and availability is rated as high, indicating a critical risk to organizational operations.
Risk & Impact Analysis
Organizations using affected versions of Cisco IOS XE face significant risks due to this vulnerability. The potential for attackers to execute arbitrary commands could lead to a complete compromise of device configurations and disrupt critical network services. With a CVSS score of 8.8, the urgency for organizations to address this vulnerability is high, and immediate patching should be prioritized.
