Adobe Warns of ‘Very Limited Attacks’ Exploiting ColdFusion Zero-Day

Adobe issues urgent warning for “very limited attacks” exploiting a zero-day vulnerability in its ColdFusion web app development platform.

Software maker Adobe on Tuesday issued an urgent warning about “very limited attacks” exploiting a zero-day vulnerability in its Adobe ColdFusion web app development platform.

Adobe’s warning was embedded in a critical-severity level advisory that contains patches for ColdFusion versions 2021 and 2018. 

“Adobe is aware that CVE-2023-26360 has been exploited in-the-wild in very limited attacks targeting Adobe ColdFusion,” the company said.  No other details on the in-the-wild compromises were provided.

Adobe’s PSIRT said the patches cover software defects that “could lead to arbitrary code execution, arbitrary file system read and memory leak.”

The company described the exploited vulnerability as a critical arbitrary file system read vulnerability with a CVSS base score of 8.6/10.   The ColdFusion update also features a second critical bug (CVSS 9.8) that could lead to code execution attacks.

In all, Adobe released patches for a whopping 106 vulnerabilities in a wide range of products, some serious enough to expose both Windows and macOS users to remote code execution attacks.
