VBulletin vulnerability analysis and mitigation

Overview

The Admin CP in vBulletin 5.6.3 allows Cross-Site Scripting (XSS) via an admincp/attachment.php&do=rebuild&type= URI (NVD). This vulnerability was discovered and disclosed in September 2020.

Technical details

The vulnerability has been assigned a CVSS v3.1 base score of 4.8 MEDIUM (Vector: CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:N) and CVSS v2.0 base score of 3.5 LOW (Vector: AV:N/AC:M/Au:S/C:N/I:P/A:N). The vulnerability is classified as CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') (NVD).

Impact

The vulnerability allows attackers to inject malicious web scripts or HTML via the attachment.php rebuild functionality in the Admin Control Panel. This could potentially lead to the execution of arbitrary web scripts or HTML in the context of the administrator's browser session (NVD).

Exploitability

The vulnerability requires high privileges (administrator access) and user interaction to be exploited. An attacker would need to have administrative access to the vBulletin installation and trick an administrator into triggering the malicious payload (NVD).

Mitigation and workarounds

The vulnerability affects vBulletin version 5.6.3. Users should upgrade to a patched version of vBulletin when available. In the meantime, administrators should exercise caution when using the attachment rebuild functionality in the Admin Control Panel (NVD).
