flyteconsole: Server-Side Request Forgery

Published Updated By the CyberSecBulletin desk

CVE-2022-24856 is a high-severity server-side request forgery vulnerability in flyteconsole from Flyteorg, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected flyteconsole versions: < 0.52.0. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 10.5% chance of exploitation within 30 days, which is in the top 4.17% of all scored CVEs.

Patch this week

EPSS places it among the vulnerabilities most likely to be exploited soon.

What to do

  1. Update Flyte Console to 0.52.0 or a later version.
  2. Read the advisory on github.com for workarounds and exact fixed builds.
  3. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

FlyteConsole is the web user interface for the Flyte platform. FlyteConsole prior to version 0.52.0 is vulnerable to server-side request forgery (SSRF) when FlyteConsole is open to the general internet. An attacker can exploit any user of a vulnerable instance to access the internal metadata server or other unauthenticated URLs. Passing of headers to an unauthorized actor may occur. The patch for this issue deletes the entire `cors_proxy`, as this is not required for console anymore. A patch is available in FlyteConsole version 0.52.0. Disable FlyteConsole availability on the internet as a workaround.

The underlying weakness: Server-Side Request Forgery

The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination.

How developers prevent this class of flaw

  • If there is a known list of applications, IP, hostname, and/or domains to which the product is allowed to communicate, then use allowlists to ensure that outgoing requests are restricted to these known entities. The allowlists could be in the application code or possibly enforced by firewalls or network segmentation.
  • If the product is expected to be able to connect to arbitrary IP addresses or domains, consider using a denylist that includes private network addresses, internal domain names, etc. The denylist could be in the application code or possibly enforced by firewalls or network segmentation.
