Organizations should schedule remediation as a priority.
Vulnerability Details
A vulnerability has been found in 1Panel-dev MaxKB up to 2.4.2. The impacted file is ui/src/chat.ts of the component MdPreview, which allows for cross-site scripting. Such manipulation can be executed remotely, leading to possible unauthorized actions performed by attackers.
The CVSS 4.0 score is 2, reflecting its low severity. The attack vector is network-based with low complexity, requiring low privileges and user interaction. The integrity impact is classified as low, while confidentiality and availability impacts are nonexistent.
The vulnerability is classified under CWE-79 (Improper Neutralization of Input During Web Page Generation) and CWE-94 (Improper Control of Generation of Code).
Technical Analysis
The root cause of this vulnerability is improper input validation in the MdPreview component, which can lead to cross-site scripting when user inputs are not adequately sanitized. The attack vector is network-based, allowing attackers to exploit the flaw remotely.
The attack complexity is low since it does not require any specialized knowledge or access to execute the attack, and only low privileges are necessary. User interaction is required, as the attack may depend on the user visiting the compromised page.
The vulnerability affects confidentiality minimally, as no sensitive data is exposed, while the integrity impact is low, with the potential for attackers to manipulate content. Availability impact is non-existent.
Risk & Impact Analysis
Organizations utilizing 1Panel-dev MaxKB must be aware of the risks posed by this vulnerability. Given its nature, attackers may leverage this vulnerability to inject malicious scripts that could compromise the integrity of web applications and potentially lead to unauthorized data access.
The urgency for remediation is classified as moderate, as organizations should schedule timely patching to prevent potential exploitation. The patch is available in version 2.5.0, which addresses the vulnerabilities identified.
Organizations are advised to monitor their systems for any unusual activities that may indicate exploitation attempts.
