CVE-2026-18279
NVD analysis in progress
Sony XAV-9500ES RTSP SETUP Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Sony XAV-9500ES devices. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of SETUP RTSP packets. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length buffer. An attacker can leverage this vulnerability to execute code in the context of the device. Was ZDI-CAN-29042.
What this means
- Exposure
- Exploitable from the adjacent network, without authentication and with no action from the victim.
- Impact
- An attacker can read sensitive data, modify or destroy data and take the service offline.
- Weakness
- A copy without a size check overwrites memory past the buffer (classic overflow).
- Likelihood
- Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.
What to doFold into the next patch cycle.
