Cloud software provider Zoho One has pushed out an update patching a zero-day vulnerability that could allow remote attackers to execute arbitrary code on affected installations of its ManageEngine Desktop Central product.
The vulnerability, CVE-2020-10189, carries a CVSS rating of 9.8 and was discovered by security researcher Steven Seeley of Source Incite. In his advisory, Seeley reported the flaw exists withing the FileStorage class and is due to the lack of proper validation of user-supplied data resulting in deserialization of untrusted data. This allows an attacker to execute code under the context of SYSTEM.
Seeley found the issue on December 12, 2019. The company was notified and pushed out its patch on March 6, 2020.
The patch, which Zoho One described as a short-term fix, can be found here.
