Overview
A Cross-Site Request Forgery (CSRF) vulnerability, identified as CVE-2025-13790, has been discovered in Scada-LTS versions up to 2.7.8.1. This vulnerability allows an attacker to potentially execute unauthorized actions on behalf of a legitimate user without their knowledge. The vendor was notified but did not respond. Public exploits are available, increasing the risk to Scada-LTS deployments.
Technical Details
CVE-2025-13790 affects an unspecified function within Scada-LTS. By crafting a malicious web page or link, an attacker can trick a logged-in user into inadvertently sending requests that perform actions on the Scada-LTS system. This could include modifying configurations, adding or deleting users, or disrupting normal operations. The vulnerability is remotely exploitable, meaning the attacker does not need direct access to the Scada-LTS server.
CVSS Analysis
- CVE ID: CVE-2025-13790
- Severity: MEDIUM
- CVSS Score: 4.3
- Vector: (Based on CVSS v3.x, details not provided but commonly includes attack vector, attack complexity, privileges required, user interaction, scope, confidentiality impact, integrity impact, and availability impact.)
A CVSS score of 4.3 indicates a medium severity vulnerability. While not as critical as high-severity issues, it still requires prompt attention due to the potential for exploitation and impact on system integrity.
Possible Impact
Successful exploitation of CVE-2025-13790 can lead to various adverse consequences, including:
- Unauthorized Configuration Changes: Attackers could modify critical system settings, potentially disrupting operations or granting themselves unauthorized access.
- Data Manipulation: Altering or deleting sensitive data within the Scada-LTS system.
- Denial of Service: Disrupting the availability of the Scada-LTS system, preventing legitimate users from accessing and controlling industrial processes.
- Privilege Escalation: Attackers could create new administrator accounts or elevate the privileges of existing accounts.
Mitigation or Patch Steps
Unfortunately, given the vendor’s lack of response, a formal patch is not currently available. Until a patch is released, consider the following mitigation strategies:
- Implement CSRF Protection: If possible, manually implement CSRF protection mechanisms within the Scada-LTS application by adding anti-CSRF tokens to all state-changing forms and requests. This requires code-level changes and expertise.
- Web Application Firewall (WAF): Deploy a Web Application Firewall (WAF) and configure it with rules to detect and block suspicious requests that may be indicative of CSRF attacks.
- User Education: Educate users about the dangers of clicking on suspicious links or opening attachments from untrusted sources. Emphasize the importance of verifying the authenticity of websites before entering credentials.
- Network Segmentation: Isolate the Scada-LTS system from other networks to limit the potential impact of a successful attack.
- Monitor Network Traffic: Implement robust network monitoring to detect unusual activity that might indicate a CSRF attack.
- Consider Alternative Solutions: If the risk is deemed too high and mitigation efforts are insufficient, consider migrating to a more secure SCADA solution.
