From Exploited flaws, HARD’s guide to the flaws being used in attacks · Checked
This article is about a flaw in TeamT5 ThreatSonar Anti-Ransomware. For every flaw being used in attacks, see Exploited flaws.

CVE-2024-7694 is a security flaw in TeamT5 ThreatSonar Anti-Ransomware. Opening a booby-trapped file can let an attacker run their own code through TeamT5 ThreatSonar Anti-Ransomware. The US Cybersecurity and Infrastructure Security Agency (CISA) added it to its catalog of flaws known to be used in attacks on 17 Feb 2026.[1]

TeamT5 ThreatSonar Anti-Ransomware is business software or equipment. Most families won’t have it, but attackers break into it to get inside companies, and from there to what those companies hold about their customers, patients and staff. TeamT5 has published a fix or advice.

Description

CISA calls it an unrestricted upload of file with dangerous type in TeamT5 ThreatSonar Anti-Ransomware. In its words: “TeamT5 ThreatSonar Anti-Ransomware contains an unrestricted upload of file with dangerous type vulnerability. ThreatSonar Anti-Ransomware does not properly validate the content of uploaded files. Remote attackers with administrator privileges on the product platform can upload malicious files, which can be used to execute arbitrary system commands on the server.”[1]

The underlying weakness is unrestricted file upload (CWE-434), in MITRE’s list of common software weaknesses.[2]

It scores 7.2 out of 10 on the Common Vulnerability Scoring System, which rates it high, scored by the organisation that published the CVE using CVSS 3.1.[2]

Affected versions

NVD’s record doesn’t list version ranges for it; TeamT5’s advisory has them[3]. CISA names the product as TeamT5 ThreatSonar Anti-Ransomware.

Most families won’t have TeamT5 ThreatSonar Anti-Ransomware; it’s for whoever looks after IT at work.

Exploitation

CISA added it to its catalog of known exploited vulnerabilities on 17 Feb 2026, 554 days after it was made public. CISA lists a flaw only when it has reliable evidence of it being exploited, and gave US federal agencies until 10 Mar 2026 to fix it.[1]

FIRST’s Exploit Prediction Scoring System, which estimates how likely a flaw is to be used in attacks in the next 30 days from what it sees across the internet, puts it at 2%. That’s in the top 22% of the flaws it scores.[4]

CISA assesses it as not automatable: each attack takes some work.

CISA doesn’t say who was attacked, or how.

Fix

TeamT5 has published a fix or advice.[3] CISA’s required action: “Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.”[1]

  1. Check whether you use it.TeamT5 ThreatSonar Anti-Ransomware is business software or equipment, so most families won’t have it. If you run a business, or work from home on company equipment, ask whoever looks after your IT.
  2. Send this page to your IT person.Ask them to confirm it’s fixed, or not in use. CISA gave US government agencies until 10 Mar 2026 to fix it.
  3. If it can’t be fixed, take it offline.CISA’s advice when there’s no fix is to stop using the product, or take it off the internet, until there is one.

You can’t fix someone else’s server, but you can watch for what follows a break-in like this: a breach notice, a password reset you didn’t ask for, or a scam message that knows things it shouldn’t. HARD watches for those for you and your family.
