Adobe has patched a critical vulnerability (CVE-2025-54236) in its Commerce and Magento Open Source platforms, dubbed SessionReaper. The flaw could allow unauthenticated attackers to take control of customer accounts via the Commerce REST API. The vulnerability was disclosed to selected customers on September 4, 2025, with a patch released on September 9, 2025. Adobe Commerce on Cloud users were protected by a WAF rule until the patch was available. The flaw is considered one of the most severe in the history of the platform, potentially leading to session forging, privilege escalation, and code execution. No exploitation in the wild has been reported, but a hotfix was leaked, which could accelerate exploitation attempts. The vulnerability impacts various versions of Adobe Commerce, Adobe Commerce B2B, Magento Open Source, and the Custom Attributes Serializable module. Adobe has also patched a critical path traversal vulnerability in ColdFusion (CVE-2025-54261).

Active exploitation of CVE-2025-5086 in DELMIA Apriso

CVE-2025-5086, a critical deserialization flaw in Dassault Systèmes DELMIA Apriso Manufacturing Operations Management (MOM) software, is being actively exploited. The vulnerability, with a CVSS score of 9.0, affects versions from Release 2020 through Release 2025. Exploitation attempts have been observed, targeting the /apriso/WebServices/FlexNetOperationsService.svc/Invoke endpoint with a Base64-encoded payload. The payload decodes to a GZIP-compressed Windows executable that deploys a malicious program designed to spy on user activities. The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has added the flaw to its Known Exploited Vulnerabilities (KEV) catalog, advising Federal Civilian Executive Branch (FCEB) agencies to apply updates by October 2, 2025. The malware, identified as Trojan.MSIL.Zapchast.gen, captures keyboard input, takes screenshots, and gathers information about active applications. This information is then sent to the attacker via various means, including email, FTP, and HTTP. The exploit involves sending a malicious SOAP request to vulnerable endpoints. The malicious requests were observed originating from the IP 156.244.33[.]162.

Akira Ransomware Group Exploits SonicWall SSL VPN Flaws

The Akira ransomware group has been actively exploiting SonicWall SSL VPN flaws and misconfigurations to gain initial access to networks. This campaign has seen increased activity since late July 2025, targeting SonicWall devices to facilitate ransomware operations. The group leverages a combination of security vulnerabilities, including a year-old flaw (CVE-2024-40766) and misconfigured LDAP settings, to bypass access controls and infiltrate networks. Organizations are advised to rotate passwords, remove unused accounts, enable multi-factor authentication, and restrict access to the Virtual Office Portal to mitigate risks. The Australian Cyber Security Centre (ACSC) has acknowledged Akira's targeting of SonicWall SSL VPNs and issued alerts about the increased exploitation of CVE-2024-40766.
