CVE-2022-36091 XWiki Platform Web Templates vulnerable to Missing Authorization, Exposure of Private Personal Information to Unauthorized Actor

What is CVE-2022-36091?

CVE-2022-36091 is a high-severity missing authorization vulnerability in Xwiki Xwiki, published on 8 Sep 2022. An attacker can exploit it over the internet without logging in, with no action from the victim.

Official description

XWiki Platform Web Templates are templates for XWiki Platform, a generic wiki platform. Through the suggestion feature, string and list properties of objects the user shouldn't have access to can be accessed in versions prior to 13.10.4 and 14.2. This includes private personal information like email addresses and salted password hashes of registered users but also other information stored in properties of objects. Sensitive configuration fields like passwords for LDAP or SMTP servers could be accessed. By exploiting an additional vulnerability, this issue can even be exploited on private wikis at least for string properties. The issue is patched in version 13.10.4 and 14.2. Password properties are no longer displayed and rights are checked for other properties. A workaround is available. The template file `suggest.vm` can be replaced by a patched version without upgrading or restarting XWiki unless it has been overridden, in which case the overridden template should be patched, too. This might need adjustments for older versions, though.
