CVE-2022-42992: n/a in n/a
Multiple stored cross-site scripting (XSS) vulnerabilities in Train Scheduler App v1.0 allow attackers to execute arbitrary web scripts or HTML via a crafted payload injected into the Train Code, Train Name, and Destination text fields.
AI Analysis
Technical Summary
CVE-2022-42992 is a medium-severity stored cross-site scripting (XSS) vulnerability identified in the Train Scheduler App version 1.0. This vulnerability arises from insufficient input sanitization and output encoding in multiple text fields, specifically the Train Code, Train Name, and Destination fields. An attacker can inject crafted malicious scripts or HTML payloads into these fields, which are then stored by the application and rendered to other users without proper sanitization. When other users view the affected pages, the malicious scripts execute in their browsers within the context of the vulnerable application. This can lead to session hijacking, credential theft, unauthorized actions on behalf of the user, or delivery of further malicious payloads. The CVSS 3.1 base score of 5.4 reflects that the attack vector is network-based (AV:N), requires low attack complexity (AC:L), but does require privileges (PR:L) and user interaction (UI:R). The scope is changed (S:C), indicating that the vulnerability affects resources beyond the initially vulnerable component. The impact on confidentiality and integrity is low, with no impact on availability. No patches or vendor information are provided, and no known exploits in the wild have been reported as of the publication date. The vulnerability is classified under CWE-79, which is the standard identifier for XSS issues.
Potential Impact
For European organizations, especially those involved in public transportation or using the Train Scheduler App or similar software, this vulnerability poses a risk of client-side attacks that can compromise user trust and data confidentiality. Attackers exploiting this flaw could hijack user sessions, steal sensitive information, or manipulate displayed data, potentially disrupting operational workflows or misleading users. While the direct impact on system availability is minimal, the reputational damage and potential regulatory consequences under GDPR for failing to protect user data could be significant. Additionally, if the app is integrated with other systems or used by critical infrastructure entities, the cascading effects could be more severe. The requirement for user interaction limits the attack to targeted or social engineering scenarios, but the network accessibility of the app increases the attack surface. The lack of patches or vendor guidance increases the urgency for organizations to implement compensating controls.
Mitigation Recommendations
Given the absence of official patches, European organizations should implement the following practical mitigations: 1) Apply rigorous input validation and output encoding on all user-supplied data fields, especially Train Code, Train Name, and Destination, to neutralize malicious scripts. 2) Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. 3) Conduct regular security assessments and code reviews focusing on injection points within the application. 4) Educate users about the risks of interacting with untrusted content and encourage cautious behavior regarding links or inputs in the app. 5) If possible, isolate the Train Scheduler App environment from critical internal networks to limit lateral movement. 6) Monitor web application logs for suspicious input patterns indicative of XSS attempts. 7) Consider deploying web application firewalls (WAFs) with rules tailored to detect and block XSS payloads targeting the affected fields. 8) Engage with the software vendor or community to obtain updates or patches and plan for timely application once available.
