CVE-2009-2453
Citrix XenApp (formerly Presentation Server) 4.5 Hotfix Rollup Pack 3 does not apply an access policy when it is defined with the Access Gateway Advanced Edition filters, which allows attackers to bypass intended access restrictions via unknown vectors.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.43%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
