Log4j Vulnerability: Mercans’ response to a critical RCE vulnerability in the widely used Log4j library.

On Dec. 9, 2021, a remote code execution (RCE) vulnerability in Apache log4j 2 was identified as being exploited in the wild. Investigation revealed that this exploitation was incredibly easy to perform. Due to the broad usage of the popular Java library, many IT Systems and SaaS providers were now at severe risk. By submitting a specially crafted request to a vulnerable system, an attacker is able to instruct that system to download and subsequently execute a malicious payload.

According to reports, with the access gained from the vulnerability, hackers could potentially exploit the application by running malicious software that could take control of a company’s system.

Just for your information, Log4j is a common logging library used by companies such as Apple, Microsoft, and Google as well as enterprise applications from CISCO, Netapp, CloudFare, Amazon and others. Logging lets developers see all the activity of an application.

Company statement towards the pressing issue

Google said it is “currently assessing the potential impact of the vulnerability for Google Cloud products and services. This is an ongoing event and we will continue to provide updates through our customer communications channels.”

NetApp stated that “the successful exploitation of this vulnerability could lead to the disclosure of sensitive information, addition or modification of data, or Denial of Service (DoS).”

Mercans vulnerability mitigation

Mercans doesn’t utilize the services of Log4j for its entire codebase.  However, it has conducted a full analysis as risk mitigation of its infrastructure in order to make sure that even the third-party tools using Log4j may not be affected. The analysis has not found any vulnerabilities and hasn’t affected the quality of services provided in any way.

Mercans makes use of military-grade security to protect its data. Its systems meet international compliance requirements including GDPR, ISO 9001, SOC 1, SOC 2, OWASP ASVS 3.0
