CVE-2024-8069Citrix Session Recording Deserialization of Untrusted Data Vulnerability
CVE-2024-8069 is a deserialization of untrusted data in Citrix Session Recording, rated medium (5.1 on CVSS 4.0).
Why this priority: Exploited in the wild: listed in CISA's KEV catalog.
Published · Updated · NVD status: Analyzed
What it is
Serialized objects from outside are turned back into live objects, which a crafted payload can abuse to run code.
How it is reached
An attacker can exploit it from the same local network segment, with an ordinary user account, and nobody has to click anything.
What an attacker gains
The direct impact is limited: partial access to data or a partial outage. In practice, this kind of flaw lets an attacker turn crafted data into code execution inside the receiving service.
Is it being exploited?
CISA added it to the Known Exploited Vulnerabilities catalog on 2025-08-25: it is being exploited in the wild. EPSS estimates a 18% chance of exploitation activity in the next 30 days, higher than 97% of scored CVEs.
What to do
- Treat it as urgent: it is on CISA's KEV list. CISA's deadline for US federal agencies: 2025-09-15.
- Upgrade Citrix Session Recording to 24.5.200.8 or later.
- Segment the networks that can reach it.
- Check exposed instances for signs of compromise, not only for the version.
Description from NVD
Limited remote code execution with privilege of a NetworkService Account access in Citrix Session Recording if the attacker is an authenticated user on the same intranet as the session recording server
What this means for your architecture.
A CVE names a product. Whether it matters depends on where that product sits in your systems: what reaches it, which trust boundary it guards and what it can reach once compromised. Veriom maps your components, their relationships and your trust boundaries from your code, cloud and delivery evidence, so you can see where a component like this sits. The radar itself does not look at your systems.
Components it touches
- Network edge devices: VPNs, firewalls, routers and gateways. They sit between the internet and internal networks, so a flaw in one is often the first step into everything behind it.
- APIs, queues and caches that accept serialized objects. The flaw sits between a message producer and the service that deserializes it.
Trust boundaries in play
- Local network segment. The attacker must share a network segment with the target.
- Between a message producer and the service that deserializes it. An attacker who crosses it can turn crafted data into code execution inside the receiving service.
Questions to answer about your own systems
- Where does Citrix Session Recording run in your systems, and at which version?
- Which network segments can reach them?
- What can it reach once compromised: which data stores, secrets and services?
