Whitepaper: Securing SAP Solutions from Log4Shell

Log4JShell is one of the most dangerous security vulnerabilities in decades. It can be exploited remotely with minimal complexity and without authentication to execute arbitrary code that could lead to the complete compromise of vulnerable applications.

Log4Shell impacts Log4J, a widely installed open-source Java logging utility. A dangerous zero-day remote code execution vulnerability in Log4J was reported in November last year. The vulnerability was patched in December and published in the National Vulnerability Database on December 12 as CVE-2021-44228.

Log4Shell was added to the Known Exploited Vulnerabilities (KEV) Catalog by the Cybersecurity and Infrastructure Security Agency (CISA) due to evidence of widespread active exploitation of the vulnerability by multiple threat actors. This includes nation state groups originating from China, Iran, Russia and North Korea. According to some reports, threat actors are exploiting the vulnerability to deploy ransomware payloads or to gain access to target networks. The access is then brokered to other threat actors.

Log4J is bundled in multiple SAP solutions including products such as SAP HANA and SAP Process Orchestration. Download the new whitepaper from Layer Seven Security to learn to mitigate and detect Log4Shell in SAP applications. The whitepaper includes a detailed breakdown of the vulnerability, guidance for patching and securing SAP solutions, and recommendations for detecting Log4shell signatures and indicators of compromise.
