CVE-2022-45970: n/a in n/a
Alist v3.5.1 is vulnerable to Cross Site Scripting (XSS) via the bulletin board.
AI Analysis
Technical Summary
CVE-2022-45970 is a Cross Site Scripting (XSS) vulnerability identified in Alist version 3.5.1, specifically exploitable via the bulletin board feature. XSS vulnerabilities arise when an application includes untrusted user input in web pages without proper validation or escaping, allowing attackers to inject malicious scripts that execute in the context of other users' browsers. In this case, the bulletin board functionality of Alist does not sufficiently sanitize input, enabling an attacker with at least low privileges (PR:L) to craft malicious payloads that require user interaction (UI:R) to trigger. The vulnerability has a CVSS 3.1 base score of 5.4, indicating a medium severity level. The vector details (AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N) reveal that the attack can be launched remotely over the network with low attack complexity, requires the attacker to have some privileges (likely a registered user), and needs the victim to interact with the malicious content. The scope is changed (S:C), meaning the vulnerability affects resources beyond the initially vulnerable component. The impact affects confidentiality and integrity to a limited extent, with no direct impact on availability. No known exploits are currently reported in the wild, and no official patches or vendor details are provided. The vulnerability is categorized under CWE-79, the standard classification for XSS issues.
Potential Impact
For European organizations using Alist 3.5.1, this vulnerability poses a risk primarily to the confidentiality and integrity of user data and sessions. Successful exploitation could allow attackers to steal session cookies, perform actions on behalf of users, or deliver malicious payloads such as keyloggers or phishing content. This could lead to unauthorized access to sensitive information or manipulation of data within the affected application. While availability is not directly impacted, the reputational damage and potential data breaches could have regulatory consequences under GDPR. Organizations relying on Alist for internal or external collaboration via bulletin boards may face increased risk of targeted attacks, especially if user privileges are not tightly controlled. The requirement for user interaction means social engineering or phishing tactics might be used to trigger the exploit. Given the medium severity and the lack of known exploits, the threat is moderate but should not be ignored, especially in environments with sensitive data or high compliance requirements.
Mitigation Recommendations
1. Implement strict input validation and output encoding on all bulletin board inputs to neutralize malicious scripts. 2. Restrict bulletin board posting privileges to trusted users and enforce the principle of least privilege to minimize the attack surface. 3. Educate users about the risks of interacting with untrusted content and encourage vigilance against suspicious links or messages. 4. Monitor bulletin board content for suspicious or anomalous posts that could indicate attempted exploitation. 5. If possible, isolate the bulletin board feature or deploy Content Security Policy (CSP) headers to restrict script execution origins and reduce XSS impact. 6. Regularly update Alist to newer versions if patches become available, and maintain an inventory of deployed versions to identify vulnerable instances. 7. Employ web application firewalls (WAFs) with rules targeting XSS patterns to provide an additional layer of defense. 8. Conduct periodic security assessments and penetration testing focusing on web input handling to detect similar vulnerabilities proactively.
