CVE-2022-42993: n/a in n/a
Password Storage Application v1.0 was discovered to contain a cross-site scripting (XSS) vulnerability via the Setup page.
AI Analysis
Technical Summary
CVE-2022-42993 is a medium severity cross-site scripting (XSS) vulnerability identified in Password Storage Application v1.0, specifically present on its Setup page. XSS vulnerabilities arise when an application includes untrusted user input in web pages without proper validation or escaping, allowing attackers to inject malicious scripts. In this case, the vulnerability allows an attacker with at least low privileges (PR:L) to execute arbitrary scripts in the context of the victim's browser. The CVSS vector indicates the attack can be performed remotely over the network (AV:N) with low attack complexity (AC:L), but requires user interaction (UI:R), such as clicking a crafted link or visiting a malicious page. The scope is changed (S:C), meaning the vulnerability affects resources beyond the initially vulnerable component, and the impact affects confidentiality and integrity partially (C:L/I:L) but not availability (A:N). Since the vulnerability is on the Setup page, it is likely accessible during initial configuration or administrative setup, which may limit exposure to authenticated users or those with access to the setup interface. No known exploits are reported in the wild, and no patches or vendor information are currently available. The vulnerability is classified under CWE-79, the standard category for XSS issues.
Potential Impact
For European organizations, this vulnerability poses a moderate risk primarily to confidentiality and integrity of data managed by the Password Storage Application. If exploited, attackers could execute scripts that steal session tokens, manipulate stored passwords, or perform actions on behalf of legitimate users, potentially leading to credential compromise or unauthorized access. The requirement for user interaction and some level of privileges reduces the likelihood of widespread exploitation but does not eliminate risk, especially in environments where the Setup page is accessible to multiple users or exposed externally. Organizations using this application to manage sensitive credentials could face targeted attacks aiming to escalate privileges or pivot within networks. The lack of a patch and vendor information complicates timely remediation, increasing the window of exposure. Additionally, the change in scope means that the impact could extend beyond the Setup page, potentially affecting other components or user sessions.
Mitigation Recommendations
Given the absence of official patches, European organizations should implement compensating controls immediately. These include restricting access to the Setup page to trusted administrators only, ideally limiting it to internal networks or VPN access. Employ web application firewalls (WAFs) with rules to detect and block typical XSS payloads targeting the Setup page. Conduct thorough input validation and output encoding on any user-supplied data if custom modifications or controls are possible. Educate users and administrators about the risk of clicking untrusted links or interacting with suspicious content related to the application. Monitor logs for unusual activity around the Setup page, such as unexpected requests or script injections. If feasible, consider isolating or replacing the vulnerable Password Storage Application with a more secure alternative until a patch is available. Regularly review vendor communications for updates or patches addressing this vulnerability.
