CVE-2022-23748
CVE-2022-23748 is a security flaw in Audinate Dante Discovery. Opening a booby-trapped file can let an attacker run their own code through Audinate Dante Discovery. The US Cybersecurity and Infrastructure Security Agency (CISA) added it to its catalog of flaws known to be used in attacks on 6 Feb 2025.[1]
Audinate Dante Discovery 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. Audinate has published a fix or advice.
Description
CISA calls it a process control in Audinate Dante Discovery. In its words: “Dante Discovery contains a process control vulnerability in mDNSResponder.exe that all allows for a DLL sideloading attack. A local attacker can leverage this vulnerability in the Dante Application Library to execute arbitrary code.”[1]
The CVE record adds: “mDNSResponder.exe is vulnerable to DLL Sideloading attack. Executable improperly specifies how to load the DLL, from which folder and under what conditions. In these scenarios, a malicious attacker could be using the valid and legitimate executable to load malicious files.”[2]
The underlying weakness is CWE-114, in MITRE’s list of common software weaknesses.
It scores 7.8 out of 10 on the Common Vulnerability Scoring System, which rates it high, scored by NVD using CVSS 3.1.[2]
Affected versions
NVD’s record doesn’t list version ranges for it; Audinate’s advisory has them[3]. CISA names the product as Audinate Dante Discovery.
Most families won’t have Audinate Dante Discovery; it’s for whoever looks after IT at work.
Exploitation
CISA added it to its catalog of known exploited vulnerabilities on 6 Feb 2025, 812 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 27 Feb 2025 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 8%. That’s in the top 6% 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
Audinate has published a fix or advice.[3] CISA’s required action: “Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.”[1]
- Check whether you use it.Audinate Dante Discovery 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.
- Send this page to your IT person.Ask them to confirm it’s fixed, or not in use. CISA gave US government agencies until 27 Feb 2025 to fix it.
- 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.
