The U.S. Cybersecurity and Infrastructure Security Company (CISA) warned of lively exploitation of a higher-severity Adobe ColdFusion vulnerability by unidentified menace actors to acquire original entry to authorities servers.
“The vulnerability in ColdFusion (CVE-2023-26360) offers as an poor obtain regulate issue and exploitation of this CVE can outcome in arbitrary code execution,” CISA stated, incorporating an unnamed federal agency was focused between June and July 2023.
The shortcoming influences ColdFusion 2018 (Update 15 and previously versions) and ColdFusion 2021 (Update 5 and previously versions). It has been tackled in variations Update 16 and Update 6, introduced on March 14, 2023, respectively.

It was included by CISA to the Recognized Exploited Vulnerabilities (KEV) catalog a working day later, citing evidence of lively exploitation in the wild. Adobe, in an advisory unveiled around that time, mentioned it’s knowledgeable of the flaw being “exploited in the wild in really confined assaults.”
The company pointed out that at the very least two community-facing servers were being compromised utilizing the flaw, each of which had been working outdated versions of the software package.
“On top of that, many commands have been initiated by the risk actors on the compromised web servers the exploited vulnerability allowed the danger actors to drop malware making use of HTTP Article instructions to the directory path associated with ColdFusion,” CISA observed.
There is proof to recommend that the malicious activity is a reconnaissance effort carried out to map the broader network, while no lateral movement or knowledge exfiltration has been observed.
In one particular of the incidents, the adversary was noticed traversing the filesystem and uploading several artifacts to the web server, such as binaries that are able of exporting web browser cookies as properly as malware built to decrypt passwords for ColdFusion information sources.
A second function recorded in early June 2023 entailed the deployment of a remote access trojan that is a modified version of the ByPassGodzilla web shell and “makes use of a JavaScript loader to infect the unit and calls for interaction with the actor-controlled server to execute actions.”
Also carried out by the adversary were tries to exfiltrate the Windows Registry documents as nicely as unsuccessfully obtain information from a command-and-control (C2) server.
“For the duration of this incident, assessment strongly implies that the menace actors likely seen the details contained in the ColdFusion seed.properties file by using the web shell interface,” CISA mentioned.
“The seed.qualities file contains the seed benefit and encryption method made use of to encrypt passwords. The seed values can also be applied to decrypt passwords. No destructive code was located on the victim procedure to reveal the menace actors tried to decode any passwords utilizing the values located in seed.houses file.”
