F5 Labs analyzes CVE-2025-23061 and its predecessor CVE-2024-53900, a CVSS 9.0 flaw in the Mongoose MongoDB client library that allows remote code execution on Node.js API servers. The bug abuses the populate method, which accepts a $where clause containing arbitrary JavaScript. The initial fix for CVE-2024-53900 blocked only top-level $w…
F5 Labs, using attack telemetry from Efflux's global sensor network, analyzed the most exploited vulnerabilities in July 2025 and found that nearly all top-scanned CVEs are HTTP-based RCE or command injection flaws in web interfaces. CVE-2017-9841 (PHPUnit) was the most exploited, followed by CVE-2023-1389 (TP-Link Archer AX21), CVE-2022-…
F5 Labs, using Efflux sensor telemetry, reports a campaign that began on 2025-06-08. One actor is exploiting TP-Link AX21 routers (CVE-2023-1389, command injection in the country query parameter) and Raisecom web interfaces (CVE-2024-7120) to deliver a new malware family named NoBooze1. Four source IPs and three stage-one hosts were rotat…
F5 Labs' January 2026 AI security roundup covers two attack developments: the Persona Bullying jailbreak and a critical LangChain serialization injection vulnerability (CVE-2025-68664) reachable through prompt injection. Persona Bullying applies human social-engineering tactics such as gaslighting, ridicule and social pressure to LLMs con…
NGINX released versions 1.30.6 (stable) and 1.31.7 (mainline) on October 14 to fix five vulnerabilities, one of which has been present in every release since May 2005. Three are memory-corruption bugs that F5 says could crash a worker process or possibly allow code execution. A fourth is a TLS session-ticket flaw that may let a forged ses…
F5 Labs published its March 2026 CASI Leaderboard update, which is now dominated by OpenAI and Anthropic. Z.ai's GLM-5 performs well on price and capability but has a weak security posture (CASI 37.56 vs 96.61 for Claude Opus 4.6 and 92.58 for GPT-5.2). The report also spotlights Sugar-Coated Poison (SCP), a multi-turn technique that grad…
Huntress researchers detailed an SEO-poisoning campaign on 13 October that harvests SSL VPN credentials through a lookalike WatchGuard download page, watchguard-vpn.net, and then delivers the legitimate, validly signed Mobile VPN with SSL installer. Earlier waves used trojanised installers, but this iteration contains no malware, so endpo…
F5 Labs, using Efflux sensor telemetry, reports on the most exploited CVEs of April 2025 and on internet-wide scanning for SparkRAT command-and-control servers. A single actor, using three IPs in DigitalOcean ASN 14061, sent identical HTTP POST requests to the SparkRAT in-place update endpoint, each IP scanning for about 13 hours and reac…
