[00:00:00]Cisco's issued an urgent security warning after discovering a maximum severity authentication bypass vulnerability actively being exploited in the wild. The flaw tracked as CVE-202620182 carries a perfect CVSS score of 10 and impacts Cisco Catalyst SD-WAN infrastructure, specifically the SD-WAN controller formerly vSmart and SD-WAN manager formerly vManage. According to Cisco, a multiple security researchers and or and multiple security researchers, the vulnerability exists within the peering authentication mechanism of vDaemon service over DTLS and TLS. This service acts as a trusted communication layer throughout the SD-WAN overlay fabric. What makes this flaw especially dangerous is that attackers do not need valid credentials.

[00:00:52]By sending specially crafted control connection requests to exposed management interfaces, a remote attacker can completely bypass authentication and gain access as an internal high-privilege user. Extremely extremely critical. Once inside, attackers can manipulate network-wide configurations using NETCONF inject rogue devices into the SD-WAN fabric intercept enterprise traffic and establish persistent access deep inside corporate environments. Cisco Talos has confirmed active exploitation tied to a threat actor actor tracked as UAT-8616.

[00:01:31]The vulnerability was originally uncovered during investigations into another SD-WAN flaw CVE-202620 uh 127.

[00:01:41]Due to the severity of the threat though, the US Cybersecurity and In- and Infrastructure Security Agency or CISA added the vulnerability to its known exploited vulnerabilities catalog and ordered federal civilian agencies to patch affected systems immediately.

[00:01:56]Cisco says there are currently no effective workarounds without upgrading.

[00:02:00]Organizations using affected SD-WAN deployments should immediately apply immediately apply Cisco's patch software versions, restrict management access to trusted IP ranges only, and ensure UDP port 12346 is not exposed directly to public internet. Administrators should also conduct immediate audits for rogue peer devices, suspicious configurations, or other indicators of compromise. Given the level of access this exploit provides, organizations should treat this as a potential network-wide compromise scenario. If your environment relies on Cisco SD-WAN infrastructure, immediate action is strongly recommended, which means do it. When the government says strongly recommended, they mean do it.
