A vulnerability in the Lobby Ambassador web-based management API of Cisco IOS XE Software could allow an authenticated, remote attacker to elevate their privileges and access management APIs that would not normally be available for Lobby Ambassador users. This vulnerability exists because parameters that are received by an API endpoint are not sufficiently validated. An attacker could exploit this vulnerability by authenticating as a Lobby Ambassador user and sending a crafted HTTP request to an affected device. A successful exploit could allow the attacker to create a new user with privilege level 1 access to the web-based management API. The attacker would then be able to access the device with these new credentials and privileges.
The severity level of this vulnerability is classified as medium, with a CVSS score of 5.4. This score indicates that while it may not be the most critical issue, it still poses a significant risk to organizations using this software. Risk to organizations includes the potential for unauthorized access to sensitive management APIs, which can lead to further exploitation and compromise of the affected systems.
Currently, there is no known public exploit for this vulnerability, and it is not actively being exploited in the wild. However, organizations should prioritize patching immediately to prevent any potential exploitation.
Organizations should schedule remediation to address this vulnerability within their patch management processes. The exploitability score is rated medium, which suggests that while the attack is not trivial, it is achievable under certain conditions.
Vulnerability Details
The official description of this vulnerability highlights the lack of sufficient validation of parameters received by the API endpoint. The affected software, Cisco IOS XE, is widely used, making this vulnerability significant for many organizations.
Technical Analysis
The root cause of this vulnerability lies in improper validation of API input parameters. Attackers may leverage this flaw by sending specifically crafted requests after authenticating as legitimate users, thereby gaining unauthorized access to sensitive management functionalities.
Risk & Impact Analysis
Real-world risk includes unauthorized access to management APIs, which could allow attackers to manipulate device configurations or access sensitive information. Organizations should assess the blast radius of this vulnerability, especially if the affected systems are exposed to untrusted networks.
