slack-morphism-rust: Exposure of Sensitive System Information Due to Uncleared Debug Information
CVE-2022-39292 is a high-severity exposure of sensitive system information due to uncleared debug information vulnerability in slack-morphism-rust from Abdolence, 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 slack-morphism-rust versions: <= 1.3.0. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.87% chance of exploitation within 30 days, higher than 59% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Check which version of slack-morphism-rust you run against the affected versions below, and install the vendor's latest release.
- Read the advisory on github.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
Slack Morphism is a modern client library for Slack Web/Events API/Socket Mode and Block Kit. Debug logs expose sensitive URLs for Slack webhooks that contain private information. The problem is fixed in version 1.3.2 which redacts sensitive URLs for webhooks. As a workaround, people who use Slack webhooks may disable or filter debug logs.

The underlying weakness: Exposure of Sensitive System Information Due to Uncleared Debug Information
The hardware product enters debug mode but does not fully clear security-sensitive values, such as keys and intermediate values in cryptographic operations.
How developers prevent this class of flaw
- Whenever debug mode is enabled, all registers containing sensitive assets must be cleared.
Timeline
- CVE record published.
- CISA published its SSVC assessment (exploitation: none, automatable: yes, technical impact: partial).
- Record last changed materially (score, affected products, status or references).
