Zimbra this week released patches for a cross-site scripting (XSS) vulnerability in Collaboration Suite that has been exploited in malicious attacks.
Tracked as CVE-2023-37580, the vulnerability was disclosed earlier this month, when Zimbra recommended manual patching for version 8.8.15 of the popular email and collaboration solution.
No CVE identifier had been issued for the flaw at the time, but Clement Lecigne from Google’s Threat Analysis Group (TAG) said that in-the-wild exploitation had been observed.
This week, Zimbra announced software updates for Zimbra Collaboration Suite versions 8.8.15, 9.0.0, and 10.0.x. A fix for the exploited security bug was included in version 8.8.15 patch 41 of the solution.
“A cross-site scripting (XSS) vulnerability that was present in the Zimbra Classic Web Client has been addressed,” Zimbra notes in its advisory.
The update resolves two other vulnerabilities in the suite, namely CVE-2023-38750, an issue leading to the exposure of internal JSP and XML files, and CVE-2023-0464, a bug “related to the verification of X.509 certificate chains that include policy constraints” in OpenSSL.
Patches for the last two flaws were included in the Zimbra Collaboration Suite versions 10.0.2 and 9.0.0 patch 34 as well. CVE-2023-37580, however, only impacts version 8.8.15 of the solution.
Additional information on the software updates can be found on Zimbra’s security center webpage.
On Thursday, the US Cybersecurity and Infrastructure Security Agency (CISA) announced that it has added CVE-2023-37580 to its Known Exploited Vulnerabilities Catalog.
“These types of vulnerabilities are frequent attack vectors for malicious cyber actors and pose significant risks to the federal enterprise,” CISA notes.
Per Binding Operational Directive (BOD) 22-01, federal agencies are required to identify vulnerabilities added to CISA’s ‘Must Patch’ list and apply the available fixes within three weeks. In this case, patches should be applied by August 17, 2023.
