Attackers compromised six Cisco VIRL-PE servers that are affected by critical SaltStack vulnerabilities.
Cisco said attackers have been able to compromise its servers after exploiting two known, critical SaltStack vulnerabilities. The flaws exist in the open-source Salt management framework, which are used in Cisco network-tooling products.
Two Cisco products incorporate a version of SaltStack that is running the vulnerable salt-master service. The first is Cisco Modeling Labs Corporate Edition (CML), which gives users a virtual sandbox environment to design and configure network topologies. The second is Cisco Virtual Internet Routing Lab Personal Edition (VIRL-PE), used to design, configure and operate networks using versions of Cisco’s network operating systems.
Hackers were able to successfully exploit the flaws incorporated in the latter product, resulting in the compromise of six VIRL-PE backend servers, according to Cisco. Those servers are: us-1.virl.info, us-2.virl.info, us-3.virl.info, us-4.virl.info, vsm-us-1.virl.info and vsm-us-2.virl.info.
