TCP packet injection in Anviz CrossChex Standard client/server channel
CVE-2026-40434 affects Anviz CrossChex Standard. The vulnerability is caused by a lack of source verification in the client/server communication channel, classified as CWE-940. Because the application does not properly verify the source of traffic on that channel, an attacker on the same network can inject crafted TCP packets into the client/server session. Successful exploitation allows the attacker to alter application traffic or disrupt it, impacting the integrity and availability of communications. The provided context does not identify a specific vulnerable function or code path.
