Attribution

This vulnerability has been reported on Intigriti by @floerer

The mail obfuscation configuration was not fully taken into account and while the mail displayed to the end user was obfuscated:

• the rest response was also containing the mail unobfuscated
• user were able to filter and sort on the unobfuscated (allowing to infer the mail content)

The consequence was the possibility to retrieve the email addresses of all users even when obfuscated.

See https://jira.xwiki.org/browse/XWIKI-20333 for the reproduction steps.

CVE-2023-34467 has a CVSS score of 7.5 (High). The vector is network-reachable, no privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (14.4.8, 14.10.4); upgrading removes the vulnerable code path.

This has been patched in XWiki 14.10.4, XWiki 14.4.8, and XWiki 15.0-rc-1.

1. What is CVE-2023-34467? CVE-2023-34467 is a high-severity security vulnerability in org.xwiki.platform:xwiki-platform-livetable-ui (maven), affecting versions >= 3.5-milestone-1, < 14.4.8. It is fixed in 14.4.8, 14.10.4.
2. How severe is CVE-2023-34467? CVE-2023-34467 has a CVSS score of 7.5 (High). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
3. Which versions of org.xwiki.platform:xwiki-platform-livetable-ui are affected by CVE-2023-34467? org.xwiki.platform:xwiki-platform-livetable-ui (maven) versions >= 3.5-milestone-1, < 14.4.8 is affected.
4. Is there a fix for CVE-2023-34467? Yes. CVE-2023-34467 is fixed in 14.4.8, 14.10.4. Upgrade to this version or later.
5. Is CVE-2023-34467 exploitable, and should I be worried? Whether CVE-2023-34467 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

6. What actually determines whether CVE-2023-34467 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
7. How do I fix CVE-2023-34467?
   • Upgrade org.xwiki.platform:xwiki-platform-livetable-ui to 14.4.8 or later
   • Upgrade org.xwiki.platform:xwiki-platform-livetable-ui to 14.10.4 or later
