Availability: None

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: None: There is no loss of confidentiality within the impacted component.
Integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: None: There is no impact to availability within the impacted component.

AI-suggested

Until a fix is available, users should apply input validation or sanitization controls on the deviceid parameter if possible and restrict access to the vulnerable functionality. Monitor vendor communications for official patches or updates.

Description

A vulnerability was detected in phpIPAM up to 1.8.3. Affected by this issue is the function create_rack_link of the file app/tools/racks/show-rack-popup.php of the component Rack Link Creation. Performing a manipulation of the argument deviceid results in cross site scripting. Remote exploitation of the attack is possible. The exploit is now public and may be used. The vendor was contacted early about this disclosure.

Impact

Successful exploitation allows an attacker to perform cross-site scripting attacks, potentially leading to script execution in the context of users interacting with the vulnerable function. This can result in limited impact such as user session hijacking or UI manipulation. The CVSS score of 4.3 reflects a low severity impact with no confidentiality or availability impact.

Summary

phpIPAM versions up to 1.8.3 contain a cross-site scripting vulnerability in the create_rack_link function within the app/tools/racks/show-rack-popup.php file. This vulnerability is due to insufficient sanitization of the deviceid parameter, which can be manipulated to execute arbitrary scripts in the context of the victim's browser. Remote exploitation is possible, and public exploit code exists. The vendor was notified early, but no patch or remediation details are provided in the available data.
