Overview
CVE-2025-0643 is a high-severity vulnerability affecting Narkom Communication and Software Technologies Trade Ltd. Co.’s Pyxis Signage software. Specifically, it’s a Stored Cross-Site Scripting (XSS) vulnerability caused by improper neutralization of user-supplied input during web page generation. This means malicious scripts can be permanently injected into the application and executed when other users interact with the compromised data.
This vulnerability affects Pyxis Signage versions up to and including 31012025.
Technical Details
The vulnerability lies in the insufficient sanitization or encoding of user input within the Pyxis Signage application. An attacker can inject malicious JavaScript code into a field (e.g., a signage display name, description, or other editable content) within the application. This malicious code is then stored in the application’s database. When a legitimate user views the signage or the compromised data, the stored script is executed in their browser, potentially allowing the attacker to:
- Steal user cookies and session tokens
- Deface the signage display
- Redirect users to malicious websites
- Compromise user accounts
- Perform actions on behalf of the user
CVSS Analysis
The Common Vulnerability Scoring System (CVSS) provides a standardized way to assess the severity of vulnerabilities. CVE-2025-0643 has a CVSS score of 7.2, indicating a HIGH severity. This score is primarily due to the following factors:
- Attack Vector (AV): Network (N) – The vulnerability can be exploited remotely over a network.
- Attack Complexity (AC): Low (L) – The vulnerability is relatively easy to exploit.
- Privileges Required (PR): Low (L) – The attacker needs only low-level privileges to inject the malicious script.
- User Interaction (UI): Required (R) – The attacker requires a user to interact with the injected script (e.g., viewing a signage page containing the malicious code).
- Scope (S): Changed (C) – An exploited vulnerability can affect resources beyond the attacker’s control.
- Confidentiality Impact (C): Low (L) – Limited disclosure of information.
- Integrity Impact (I): Low (L) – Limited modification of data.
- Availability Impact (A): Low (L) – Limited disruption of services.
Possible Impact
Successful exploitation of this Stored XSS vulnerability could have serious consequences:
- Data Breach: Sensitive user data, including cookies and session tokens, could be stolen.
- Account Takeover: Attackers could gain control of user accounts.
- Reputation Damage: The compromised signage could display inappropriate or malicious content, damaging the organization’s reputation.
- Malware Distribution: Users could be redirected to websites hosting malware.
Mitigation and Patch Steps
To mitigate the risk of CVE-2025-0643, the following steps are recommended:
- Apply the Patch: Narkom Communication and Software Technologies Trade Ltd. Co. should release a patch to address this vulnerability. Apply the patch as soon as it becomes available. Contact Narkom support for the latest information.
- Input Validation: Implement robust input validation and sanitization on all user-supplied data. Use escaping functions appropriate for the output context (e.g., HTML escaping for HTML output).
- Output Encoding: Encode all data before rendering it in the web page. This will prevent malicious scripts from being executed.
- Web Application Firewall (WAF): Deploy a WAF to detect and block XSS attacks. Configure the WAF with appropriate rules to protect against this type of vulnerability.
- Regular Security Audits: Conduct regular security audits and penetration testing to identify and address vulnerabilities in the Pyxis Signage application.
- User Education: Educate users about the risks of clicking on suspicious links or entering data into untrusted websites.
