CISA Adds Four Actively Exploited Vulnerabilities to KEV, Sets May 8 Deadline

Summary
CISA added four actively exploited flaws affecting SimpleHelp, Samsung MagicINFO 9 Server, and D-Link DIR-823X routers to KEV. Federal agencies should apply fixes or retire affected routers by May 8, 2026.
Key points
- CISA added four vulnerabilities to its Known Exploited Vulnerabilities catalog, citing evidence of active exploitation.
- CVE-2024-57726 lets low-privileged SimpleHelp technicians create overly privileged API keys that can enable server-admin escalation.
- CVE-2024-57728 and CVE-2024-7399 are path traversal flaws that can write arbitrary files; the article says they may enable code execution or system-level file writes.
- CVE-2025-29635 is a command injection flaw in end-of-life D-Link DIR-823X routers, exploitable through a POST request to /goform/set_prohibiting.
- Earlier reporting linked exploitation of the SimpleHelp flaws to ransomware activity, including a campaign attributed to DragonForce; the article notes CISA lists ransomware use as unknown.
- MagicINFO exploitation has previously been linked to Mirai activity; Akamai reported attempts against D-Link devices to deliver a Mirai variant called tuxnokill.
- Federal agencies are advised to apply fixes or, for the end-of-life D-Link routers, discontinue use by May 8, 2026.
