Security News > 2023 > July > Adobe fixes patch bypass for exploited ColdFusion CVE-2023-29298 flaw
Adobe released an emergency ColdFusion security update that fixes critical vulnerabilities, including a fix for a new zero-day exploited in attacks.
As part of today's out-of-band update, Adobe fixed three vulnerabilities: a critical RCE tracked as CVE-2023-38204, a critical Improper Access Control flaw tracked as CVE-2023-38205, and a moderate Improper Access Control flaw tracked as CVE-2023-38206.
Adobe says the CVE-2023-38205 flaw was abused in limited attacks.
"Adobe is aware that CVE-2023-38205 has been exploited in the wild in limited attacks targeting Adobe ColdFusion," explains the Adobe security bulletin.
The CVE-2023-38205 flaw is a patch bypass for the fix for CVE-2023-29298, a ColdFusion authentication bypass discovered by Rapid7 researchers Stephen Fewer on July 11th. On July 13th, Rapid7 observed attackers chaining exploits for the CVE-2023-29298 and what appeared to be the CVE-2023-29300/CVE-2023-38203 flaws to install webshells on vulnerable ColdFusion servers to gain remote access to devices.
Critical ColdFusion flaws exploited in attacks to drop webshells.
