VULNERABILITY IN END-OF-TRAIN AND HEAD-OF-TRAIN REMOTE LINKING PROTOCOL

CISA revealed a critical vulnerability (CVE-2025-1727) in railroad End-of-Train and Head-of-Train protocols that allows attackers to send unauthorized brake commands via software-defined radio. Affecting all U.S. rail industry versions, the vulnerability stems from weak BCH checksum authentication that can disrupt operations or cause sudden stops. The American Railroads are developing new systems, while manufacturers like Hitachi Rail, Wabtec, and Siemens should adopt network isolation and secure remote access controls.

PATCH IMMEDIATELY: CVE-2025-25257 POC ENABLES REMOTE CODE EXECUTION ON FORTINET FORTIWEB

A serious SQL injection vulnerability (CVE-2025-25257) has been identified in Fortinet FortiWeb. The flaw allows unauthenticated attackers to execute remote code by writing malicious files to the server's filesystem, potentially leading to full remote code execution. Fortinet has issued patches for versions 7.6.4, 7.4.8, 7.2.11, and 7.0.11. Immediate application of these updates is strongly recommended due to publicly available exploits.

03STRATEGIES & TACTICS

FOOLING THE SANDBOX: A CHROME-ATIC ESCAPE

The security researcher in this blog analyzes CVE-2024-30088, a Windows kernel vulnerability that allows privilege escalation. They successfully chained it to escape Chrome's renderer sandbox by bypassing integrity level checks and job object restrictions. The exploit overwrites security descriptors to gain system privileges, then spawns a privileged shell with full control.

SCANNING FOR POST-QUANTUM CRYPTOGRAPHIC SUPPORT

Anvil Secure's PQCscan is a free scanner that identifies SSH and TLS servers supporting Post-Quantum Cryptographic (PQC) algorithms. The tool scans for standardized PQC algorithms, such as X25519MLKEM768, and generates HTML reports to help organizations prepare for mandatory PQC compliance deadlines between 2030 and 2035. Available on GitHub under a BSD license, it currently performs capability detection without full handshake testing.

CYBERSECURITY (ANTI)PATTERNS: FRICTIONWARE

Frictionware is security tooling that forces security teams to spend more time onboarding the tool than focusing on generating results. Some anti-patterns that lead to frictionware are: complex onboarding, weak value proposition, and a lack of integration with existing tools. Frictionware can be avoided by avoiding onboarding altogether, focusing on build-in instead of opt-in, using forcing functions to compel onboarding when required, and working within existing centers of data and attention.

LIBRARIES ARE UNDER-USED, LLMS MAKE THIS PROBLEM WORSE

Libraries are underutilized in favor of custom code. This is due to engineers preferring to write code rather than read documentation, underestimating the problem, and organizations that reward complex internal projects over using libraries. LLMs can further this issue by rapidly generating code that is not as well-tested or understood as the more well-known libraries.
