Update on the recent Apache Log4j2 vulnerabilities - Impact on Zoho Analytics On Premise Deployments

Dear Users,

Three high severity vulnerabilities (CVE- 2021-44228, CVE-2021-45105 and CVE-2021-45046), impacting multiple versions of Apache Log4j utility, was disclosed publicly on December 9, 2021. We have found no evidence of any successful exploitation in Zoho Analytics On Premise software as of today. We are continuing to analyse the issue and will provide updates of any new findings.

However the affected log4j version is present within Zoho Analytics On Premise as a bundled dependency, hence we strongly recommend all our customers to follow the below steps as a precautionary measure:

Linux users:

Open a terminal and navigate to "Analytics/lib/".
Execute the command "zip -q -d log4j-core-*.jar org/apache/logging/log4j/core/lookup/JndiLookup.class".
Restart Zoho Analytics On Premise service.

Windows users:

Download and install 7-Zip from the 7-Zip home page
After installing 7-Zip, open a command prompt and navigate to the 7-Zip installation folder (ex: C:\Program Files\7-Zip\).
Now execute the command: "7z d <Zoho_Analytics_installed_Location>\Analytics\lib\log4j-core-2.7.jar org\apache\logging\log4j\core\lookup\JndiLookup.class". This will look like "7z d C:\Zoho\Analytics\lib\log4j-core-2.7.jar org\apache\logging\log4j\core\lookup\JndiLookup.class"
Restart Zoho Analytics On Premise service.

Note: These vulnerabilities will be fixed in Zoho Analytics On Premise from build 5070 (upcoming). The above steps are applicable only if your Zoho Analytics On Premise is on build 5000, 5010, 5020, 5030, 5050, and 5060. The rest of the Zoho Analytics On Premise builds are not affected.

Important Note: Zoho Analytics cloud service is also not affected by these vulnerabilities. Please refer to this link for more details on this.
