On November 6, 2024, Wordfence researcher István Márton disclosed CVE-2024-10924 — a CVSS 9.8 authentication bypass in Really Simple Security, the plugin securing four million WordPress sites, whose two-factor onboarding endpoint failed to validate the requesting user, granting attackers admin sessions on sites with incomplete 2FA enrollment. Patched same-day in 9.1.2, NVD-published November 14, the flaw became 2024's definitive case study in security-plugin risk. This account walks the vulnerable code path, the four-million-site patch sprint, and why the ecosystem's auth surface extends far past WordPress core.

On November 6, 2024, F5 disclosed a pair of critical bugs in BIG-IP Next Central Manager shipped in its SPK fabric: CVE-2024-23327, an unauthenticated privilege-escalation path reachable via REST API, and CVE-2024-23328, a missing-authentication flaw letting attackers create arbitrary administrator accounts. Together they enable full takeover of a management node that itself commands a fleet of application delivery hardware. This account walks both paths, the same-day patches, and the uncomfortable lineage going back to CVE-2022-1388's iControl REST flaw.

On October 16, 2024, Ivanti disclosed two vulnerabilities in Endpoint Manager (EPM) chained for pre-auth remote code execution: CVE-2024-29224, an unauthenticated SSRF rated 9.6, and CVE-2024-29226, a path traversal in a downstream service. The week's disclosure calendar placed it days after FortiManager's FortiJump and amid a year of Ivanti security crises — from January's Connect Secure zero-days to September's Cloud Service Appliance flaw. This account explains the chain mechanics, why consortium defenders pushed urgent patching, and the management-plane pattern of 2024.

On October 23, 2024, Fortinet confirmed CVE-2024-47575 — a CVSS 9.8 missing-authentication flaw in the FortiManager FGFM protocol that China-nexus actor UNC5850 had exploited since summer to jump from exposed managers into fleets of managed FortiGates with a custom DeepMove implant. CISA KEV-listed it within days, forcing two-week patch deadlines across federal and enterprise fleets. This account reconstructs the protocol bug, the DeepMove persistence, the fleet-jump blast radius, and the management-plane hardening it made mandatory.

CUPS RCE: The Linux Printing Story That Went Viral Before CVEs Landed

In late September 2024, researcher Simone Margaritelli disclosed a chain of CUPS vulnerabilities — CVE-2024-47076, CVE-2024-47176 and siblings — allowing same-network attackers to register malicious printers and achieve code execution as the lp user via broadcast-trusting auto-configuration. Preceded by a hype-teaser countdown that split the community, the episode became the year's clearest study in disclosure-process dysfunction, severity theater, and the quiet ubiquity of trust-the-LAN daemons. This account covers the chain mechanics, the honest exposure math, and what to disable today.

On September 25, 2024, researchers Karan Saini and Sam Curry published an access-control flaw in Kia's dealer and consumer web infrastructure: given only a license plate, an attacker could register an account with remote lock, unlock, start, stop, locate and horn control over 2014-2025 connected vehicles they did not own. Kia patched in August before disclosure. This account walks the plate-to-command chain, the ownership-verification gap, the threat model for tracking and theft, and the automotive-API authorization lesson that outlasts the brand.

On August 21-22, 2024, SolarWinds shipped 12.8.3 HF1 for Web Help Desk and disclosed CVE-2024-28986 — an unauthenticated Java deserialization flaw rated CVSS 9.8 that delivers pre-auth remote code execution on internet-facing instances. Within days PoC code circulated in exploitation attempts, and on August 26 CISA added it to the Known Exploited Vulnerabilities catalog, making patching mandatory across federal networks. This account covers the bug mechanics, the four-day disclosure-to-KEV sprint, and the uncomfortable optics of a SolarWinds product back in emergency-cycle headlines.

Polyfill.io Hijack: 100,000+ Sites Inherited a Malicious Script

When Sansec disclosed in late June 2024 that the polyfill.io domain had been sold and its hosted script rewritten to inject mobile-only scam redirects, hundreds of thousands of embedded sites — WordPress themes among them — discovered they had inherited an implant, invisible to desktop QA by design. This account traces the Funnull acquisition chain, the conditional payload mechanics, Cloudflare's mirror intervention, the DNS-harassment retaliation, the 2025 arrests, and the inventory lesson every site owner still owes themselves.

On April 12, 2024, WatchTowr disclosed CVE-2024-3400 — a CVSS 10.0 pre-auth command injection in PAN-OS GlobalProtect that state-sponsored actors had exploited since late March by chaining a cookie-controlled file write into Tcl execution as root. This account walks the two-flaw exploit chain, the scramble after the 10.2.9-h1 hotfix, CISA's KEV clock, config-hidden persistence that survived reboots, the mitigation-versus-remediation confusion, and why 2024 made appliances patch with server-grade urgency.

March 2024's CVE-2024-27198 let unauthenticated attackers mint admin accounts on self-hosted TeamCity CI servers, converting every connected build agent into attacker-controlled execution holding source, secrets and signing keys. This piece covers the alternate-path authentication bypass, the companion path traversal, the ransomware crews that queued within days, and the year's hard-learned rule that build infrastructure deserves domain-controller-grade security.

February 2024's CVE-2024-1709 let anyone add administrative accounts to self-hosted ScreenConnect servers — a setup-wizard path traversal that converted remote-support consoles into ransomware deployment platforms within 72 hours of disclosure. This account covers the twinned vulnerabilities, why MSP-hosted instances multiplied the blast radius across client fleets, the observed ransomware sequences, and the hard questions RMM vendors faced about unauthenticated wizard endpoints.

January 2024 opened with the year's first appliance crisis: two pre-authentication zero-days in Ivanti Connect Secure that nation-state actors had already exploited, followed by integrity-check failures and a reset wave across thousands of enterprise VPNs. This account covers CVE-2023-46805 and CVE-2024-21887, the mass exploitation between disclosure and patch, the customers whose breaches surfaced weeks later, and why edge appliances became the year's most contested patch surface.
