EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
Description
DisCatSharp is a Discord API wrapper for .NET. Users of versions 9.8.5, 9.8.6, 9.9.0 and previously published prereleases of 10.0.0 who have used either one of the two RequireDisCatSharpDeveloperAttributes or the BaseDiscordClient.LibraryDeveloperTeam have potentially had their bot token sent to a web server not affiliated with Discord. This server is owned and operated by DisCatSharp's development team. The tokens were not logged, yet it is still advisable to reset the tokens of potentially affected bots. 9.9.1 has been released to patch the issue for the current stable release and the current 10.0.0 prereleases are also no longer affected. Users unable to upgrade should remove all uses of the two RequireDisCatSharpDeveloperAttributes and all direct calls to BaseDiscordClient.LibraryDeveloperTeam.
Affected Products
discatsharpaitsysDetection & mitigation playbook
Vendor / applianceDetect
Inventory every aitsys discatsharp deployment and check each version against the affected-products list above. Because the exploit targets the running system rather than your application code, also watch for exploitation at the network and runtime layer — O3 flags the exploit behaviour from runtime telemetry and egress traffic even before a vulnerable build is confirmed.
Fix
Apply the aitsys discatsharp security patch or hotfix for CVE-2022-24849 on the affected version, following the vendor advisory for your exact build.
Workarounds
Cut exposure now: restrict the management/admin interface to trusted networks, segment the device, and apply the vendor's recommended configuration mitigations and any WAF/IPS signature. O3's runtime protection blocks the exploit chain at execution, holding the line on unpatched or end-of-life systems until you can patch.
How O3 protects you
O3 detects and blocks CVE-2022-24849 exploitation at runtime: eBPF exploit-chain detection, plus L7 egress monitoring that catches the post-exploitation callback and severs the attacker's outbound channel.
Tailored to CVE-2022-24849. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2022-24849 being exploited in your environment?
O3's eBPF runtime sensors and L7 egress monitoring detect and block the CVE-2022-24849 exploit chain at execution — protecting unpatched and end-of-life systems until the vendor patch is applied.
