CVE-2024-8069
CVE-2024-8069 is a security flaw in Citrix Session Recording, the gateway companies use to let staff reach internal apps from outside. Someone who already has a way in can use Citrix Session Recording to run their own code. The US Cybersecurity and Infrastructure Security Agency (CISA) added it to its catalog of flaws known to be used in attacks on 25 Aug 2025.[1]
Citrix Session Recording 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. Fixed in version 24.5.200.8, CU9 hotfix 19.12.9100.6, CU5 hotfix 22.03.5100.11 and CU1 hotfix 24.02.1200.16 of Citrix Session Recording.
Description
CISA calls it a deserialization of untrusted data in Citrix Session Recording. In its words: “Citrix Session Recording contains a deserialization of untrusted data vulnerability that allows limited remote code execution with privilege of a NetworkService Account access. Attacker must be an authenticated user on the same intranet as the session recording server.”[1]
The underlying weakness is deserialization of untrusted data (CWE-502), in MITRE’s list of common software weaknesses.[2]
It scores 8.0 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 lists these fixed versions: in each line, everything before the version shown is affected.[2]
| Product | Fixed in |
|---|---|
| Citrix Session Recording | 24.5.200.8 |
| Citrix Session Recording | CU9 hotfix 19.12.9100.6 |
| Citrix Session Recording | CU5 hotfix 22.03.5100.11 |
| Citrix Session Recording | CU1 hotfix 24.02.1200.16 |
Most families won’t have Citrix Session Recording; it’s for whoever looks after IT at work.
Exploitation
CISA added it to its catalog of known exploited vulnerabilities on 25 Aug 2025, 286 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 15 Sep 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 21%. That’s in the top 3% 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
Citrix 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]
- Check whether you use it.Citrix Session Recording 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 (fixed in version 24.5.200.8, CU9 hotfix 19.12.9100.6, CU5 hotfix 22.03.5100.11 and CU1 hotfix 24.02.1200.16 of Citrix Session Recording), or not in use. CISA gave US government agencies until 15 Sep 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.
