This vulnerability only impacts the on-premise SWG installations. Customers using the Cloud-only setup aren't impacted. The exploit depends on how static content in the block pages is served. CVE-2023-0214: A cross-site scripting vulnerability in Skyhigh SWG in main releases 11.x prior to 11.2.6, 10.x prior to 10.2.17, and controlled release 12.x prior to 12.0.1 allows a remote attacker to craft SWG-specific internal requests with URL paths to any third-party website, causing arbitrary content to be injected into the response when accessed through SWG. This is possible owing to SWG improperly neutralizing the input URL parameters and creating a HTTP response for a carefully constructed URL: For further information see: CVE-2023-0214 (cve.mitre.org) Remediation To remediate this issue, update to the latest version of the branch that you're using.
Download and Installation Instructions: All documentation and software relating to this and other SWG releases can be found at Acknowledgments We credit the Additional details from the reporter will be provided at a future date at this URL: Frequently Asked Questions How do I know if my product is vulnerable or not? Use the following instructions for SWG:
Common Vulnerability Scoring System (CVSS) is the result of the National Infrastructure Advisory Council's effort to standardize a system of assessing the criticality of a vulnerability. This system offers an unbiased criticality score between 0 and 10 that customers can use to determine how critical a vulnerability is and plan accordingly. For more information, visit the CVSS website. When calculating CVSS scores, we've adopted a philosophy that fosters consistency and repeatability. Our guiding principle for CVSS scoring is to score the exploit under consideration by itself. We consider only the immediate and direct impact of the exploit under consideration. We don't factor into a score any potential follow-on exploits that might be made possible by the successful exploitation of the issue being scored. What are the CVSS scoring metrics?
All Security Bulletins are published on our Knowledge Center. Security Bulletins are retired (removed) once a product is both End of Sale and End of Support (End of Life). How do I report a product vulnerability to you? If you have information about a security issue or vulnerability with a product, follow the instructions provided in KB95563 - Report a vulnerability. How do you respond to this and any other reported security flaws? Our key priority is the security of our customers. If a vulnerability is found within any of our software or services, we work closely with the relevant security software development team to ensure the rapid and effective development of a fix and communication plan. We only publish Security Bulletins if they include something actionable such as a workaround, mitigation, version update, or hotfix. Otherwise, we would simply be informing the hacker community that our products are a target, putting our customers at greater risk. For products that are updated automatically, a non-actionable Security Bulletin might be published to acknowledge the discoverer. To view our PSIRT policy, see KB95564 - About PSIRT.
