NULL Pointer Dereference

CVE-2024-3184

Summary

Multiple NULL Pointer Dereference vulnerabilities were discovered in GoAhead Web Server up to version 6.0.0 when compiled with the ME_GOAHEAD_REPLACE_MALLOC flag. This allows remote attackers to cause a crash and a denial of service via malicious requests.

Impact

In case the ME_GOAHEAD_REPLACE_MALLOC compilation flag is enabled and a memory notifier is not implemented to handle allocation failures, a remote unauthenticated attacker may send malicious requests to trigger a crash and cause a Denial of Service (DoS) condition over the service.

Research Projects

TRITON

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.

GreyEnergy

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 62351

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.
