Security Flaw in Oracle POS systems discovered

Researchers at ERPScan have discovered a new security flaw in the Oracle Micros Point-of-Sale (POS) systems that has left over 300,000 systems vulnerable to attack from hackers.

It was discovered in September 2017 by Dmitry Chastuhin, a security researcher, and was named “CVE-2018-2636”.

Oracle has already issued updates for this issue earlier in the month but due to companies’ fear of unstable patches and losses, it is suspected that it may take months for the patch to reach affected systems.

According to Chastuhin, the POS malware enables hackers to collect configuration files from the systems and gain access to the server.

Hackers can also exploit the flaw remotely using carefully crafted HTTP requests. Many of the vulnerable systems have already been misconfigured to allow such access and are available online to be easily exploited if the patches aren’t used soon.

Patches for the flaw were made available in January 2018 in Oracle’s Critical Patch Update (CPU). More information on the bug can be found here.
