CVE-2024-3187
This issue tracks 2 Use After Free (UAFs) vulnerabilities and 1 Double Free vulnerability discovered in Goahead versions <= 6.0.0. These issues are caused by JST values not being nulled when they get freed while performing parsing operation over JST templates. This issue occurs when attempting to process malicious JST server-side templates.
In case the ME_GOAHEAD_JAVASCRIPT compilation flag is enabled and a malicious user is capable of controlling the content of JST templates interpreted at runtime, a remote unauthenticated attacker may attempt to leverage the memory corruptions to either trigger a crash and cause a Denial of Service (DoS) condition over the service or attempt to gain code execution. The latter scenario is extremely context dependent and is not guaranteed to succeed.

“Threat actors love finding new ways to attack critical infrastructure. We love finding new ways to detect their malware before damage occurs.”
TRITON is the first known cyberattack that directly interacted with a Safety Instrumented System (SIS). Labs reverse engineered the TriStation suite of software and delivered a report and two free tools for security researchers. This research was presented at Black Hat USA 2018.
The Labs team reverse engineered the GreyEnergy malicious document (maldoc) that leads to the installation of the malware (backdoor) on a victim’s network. Project outcomes include a report, multiple blogs and two free tools for security researchers.
IEC Working Group 15 (WG15) is developing technology standards for secure-by-design power systems. Labs contributes to the standards and has demonstrated how they can be used to identify hard-to-detect cyberattacks. Research from this effort was presented at Black Hat USA 2019.
