CVE-2021-29501: Remote code execution in ticketer

Ticketer is a command based ticket system cog (plugin) for the red discord bot. A vulnerability allowing discord users to expose sensitive information has been found in the Ticketer cog. Please upgrade to version 1.0.1 as soon as possible. As a workaround users may unload the ticketer cog to disable the exploitable code.

Security readout for executives and security teams

Plain-English summary

CVE-2021-29501 affects the Ticketer cog for the Red Discord Bot. A Discord user with some level of access could trigger vulnerable Ticketer behavior that may expose sensitive information and affect integrity. The vendor advises upgrading to 1.0.1 or unloading the cog as a workaround.

Executive priority

Prioritize remediation for any Discord bot using Ticketer, especially in public or semi-public servers. The fix is straightforward, and the stated impact includes sensitive information exposure and high integrity risk.

Technical view

The issue is tracked as CWE-74 in Dav-Git Dav-Cogs Ticketer versions before 1.0.1. CVSS 3.1 is 8.1: network exploitable, low attack complexity, low privileges required, no user interaction, unchanged scope, with high confidentiality and integrity impact and no availability impact.

Likely exposure

Exposure is limited to environments running Red Discord Bot with the Dav-Git Dav-Cogs Ticketer cog below version 1.0.1. Organizations not using that cog are not indicated as affected by the supplied sources.

Exploitation context

The supplied bundle does not show CISA KEV listing or public active exploitation evidence. The CVSS vector indicates a low-privileged remote user can trigger the issue without user interaction, so internet-facing Discord communities using the cog should treat it seriously.

Researcher notes

Evidence is strongest for affected version range, CVSS characteristics, and vendor remediation. The bundle contains inconsistent wording between remote code execution and sensitive information exposure, so avoid asserting exploit mechanics beyond CWE-74 and the published impacts.

Mitigation direction

  • Upgrade Dav-Cogs Ticketer to version 1.0.1 or later.
  • Unload the Ticketer cog until the upgrade is complete.
  • Review the vendor advisory before re-enabling Ticketer.
  • If exposure is suspected, identify and rotate affected secrets.
  • Check vendor guidance for any additional remediation notes.

Validation and detection

  • Inventory Red Discord Bot instances and installed cogs.
  • Confirm whether Dav-Cogs Ticketer is installed and enabled.
  • Verify Ticketer is version 1.0.1 or later.
  • Confirm the Ticketer cog is unloaded where upgrade is pending.
  • Review bot logs for unusual Ticketer-related activity.
