A vulnerability in the deep packet inspection (DPI) engine of Cisco SD-WAN vEdge Routers could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to improper processing of FTP traffic. An attacker could exploit this vulnerability by sending crafted FTP packets through an affected device. A successful exploit could allow the attacker to make the device reboot continuously, causing a DoS condition.
CVE-2020-3369
This high-severity CVE scores 7.5 under NVD CVSS v3. EPSS exploit probability: 1.2%, top 21% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
- High severity, but no confirmed exploitation yet
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
