Issue
-
We would like to know whether there are any strings to search for in log files, to check if any of the following vulnerabilities have been exploited in our environment?
- LSV-1237 / CVE-2023-42628
- LSV-1236 / CVE-2023-42627
- LSV-1194 / CVE-2023-44310
Resolution
- The referenced vulnerabilities are all XSS (Cross-Site Scripting) vulnerabilities that can be exploited in certain, unpatched Liferay versions.
-
All three of them are stored XSS vulnerabilities, meaning the content (usually a malicious script) is saved into the database. If you suspect you may have been affected by such an exploit, you may want to check the affected database tables for any rogue data/scripts instead of the log files.
