Technical Analysis
Lots of advanced-ish threat notifications this week…Citrix published a security advisory and a companion blog on this zero-day bug today, noting that it’s been exploited in the wild. The NSA also released information about APT 5 targeting Citrix ADC installations; their bulletin includes threat intel.
ADC is always a nice target, and often hangs out on the internet. Leaving “Exploitability” as a medium for now since there’s not a ton on the vuln inself, other than that it’s SAML-related. I’d expect more vuln details out on this one shortly, and probably a rise in exploitation—just in time for the holidays.
