SAP has patched a significant vulnerability impacting the LM Configuration Wizard ingredient in NetWeaver Application Server (AS) Java system, making it possible for an unauthenticated attacker to consider control of SAP programs.
The bug, dubbed RECON and tracked as CVE-2020-6287, is rated with a utmost CVSS score of 10 out of 10, possibly impacting about 40,000 SAP consumers, in accordance to cybersecurity agency Onapsis, which uncovered the flaw.
“If efficiently exploited, a distant, unauthenticated attacker can acquire unrestricted access to SAP systems as a result of the development of high-privileged people and the execution of arbitrary functioning program instructions with the privileges of the SAP service consumer account, which has unrestricted entry to the SAP databases and is ready to execute application upkeep actions, these kinds of as shutting down federated SAP programs,” the US Cybersecurity and Infrastructure Security Agency (CISA) claimed in an advisory.
“The confidentiality, integrity, and availability of the knowledge and procedures hosted by the SAP application are at chance by this vulnerability,” it included.
