1 minute read
Speak With A Security Expert Now

THE THREAT

The exploit pack CANVAS, from security services provider Immunity, has been leaked online. CANVAS version 7.26 (released in September 2020) contains over 800 different exploits for a wide variety of vulnerabilities.

This leak decreases the complexity of developing and running exploits, empowering low-skilled actors with “point and click attacks.” Overall, this leak does not introduce any zero-day exploits, however the risk of exploitation for known vulnerabilities is greater due to the availability of exploit code in the leaked CANVAS product. Organizations are encouraged to review the targeted CVEs below and ensure patches or mitigations are in place.
