CVE-2024-10206 B&R Industrial Automation GmbH CVE debrief

Who should care

Operators and administrators of B&R APROL deployments, especially environments where the APROL Web Portal is reachable from less-trusted networks. OT/ICS security teams and defenders responsible for patching, access control, and exposure review should treat this as relevant even though the CVSS score is medium.

Technical summary

The advisory describes an SSRF condition in the APROL Web Portal in B&R APROL <4.4-00P5. The reported attack vector is network-based and unauthenticated, with low attack complexity and no user interaction required (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N). The primary impact identified in the supplied data is limited confidentiality impact. Remediation guidance in the advisory is to apply the patch or upgrade to a non-vulnerable version, and to change secrets/passwords after updating because some listed vulnerabilities may affect credentials.

Defensive priority

Medium priority. Remediate any exposed or broadly reachable APROL Web Portal instance promptly, with highest attention on systems accessible from untrusted networks or integrated into sensitive OT environments.

Recommended defensive actions

• Upgrade B&R APROL to version 4.4-00P5 or later, or apply the vendor patch if that is the supported remediation path.
• Confirm whether any deployed APROL Web Portal instances are running a vulnerable version before and after maintenance.
• Review network exposure for the APROL Web Portal and restrict access to trusted management networks where possible.
• Apply the vendor's post-update guidance and change relevant secrets/passwords after updating.
• Validate that the installed product version matches the vendor's documented remediation state and retain evidence of patch completion.

Evidence notes

The supplied CISA CSAF source for ICSA-25-093-05 states: affected product is 'B&R APROL < 4.4-00P5'; vulnerability description is 'A Server-Side Request Forgery vulnerability in the APROL Web Portal used in B&R APROL <4.4-00P5 may allow an unauthenticated network-based attacker to force the web server to request arbitrary URLs.' The same source includes CVSS 3.1 vector AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N and remediation text recommending patching or upgrading to a non-vulnerable version, with a post-update recommendation to change secrets/passwords. The record also links official CISA and vendor references, but the supplied corpus does not include their full contents.
