SCA: security update for tailscale.com/cmd (GHSA-qccm-wmcq-pwr6)

high Tenable Cloud Security Plugin ID 418051

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - A vulnerability identified in the Tailscale client allows a malicious website to access the peer API,
 which can then be used to access Tailscale environment variables. In the Tailscale client, the peer API
 was vulnerable to DNS rebinding. This allowed an attacker-controlled website visited by the node to rebind
 DNS for the peer API to an attacker-controlled DNS server, and then making peer API requests in the
 client, including accessing the node’s Tailscale environment variables. An attacker with access to the
 peer API on a node could use that access to read the node’s environment variables, including any
 credentials or secrets stored in environment variables. This may include Tailscale authentication keys,
 which could then be used to add new nodes to the user’s tailnet. The peer API access could also be used to
 learn of other nodes in the tailnet or send files via Taildrop. All Tailscale clients prior to version
 v1.32.3 are affected. Upgrade to v1.32.3 or later to remediate the issue. (CVE-2022-41925)
