CISA Adds One Known Exploited Vulnerability to Catalog

All CISA Advisories · Apr 29, 2025

CISA has added one new vulnerability to its Known Exploited Vulnerabilities Catalog, based on evidence of active exploitation. CVE-2025-31324 SAP NetWeaver Unrestricted File Upload Vulnerability These types of vulnerabilities are frequent attack vectors for malicious cyber actors and pose significant risks to the federal enterprise. Binding Operational Directive (BOD) 22-01: Reducing the Significant Risk of Known Exploited Vulnerabilities established the Known Exploited Vulnerabilities Catalog as a living list of known Common Vulnerabilities and Exposures (CVEs) that carry significant risk to the federal enterprise. BOD 22-01 requires Federal Civilian Executive Branch (FCEB) agencies to remediate identified vulnerabilities by the due date to protect FCEB networks against active threats. See the BOD 22-01 Fact Sheet for more information. Although BOD 22-01 only applies to FCEB agencies, CISA strongly urges all organizations to reduce their exposure to cyberattacks by prioritizing timely remediation of Catalog vulnerabilities as part of their vulnerability management practice. CISA will continue to add vulnerabilities to the catalog that meet the specified criteria.

Tenable Blog · Apr 25, 2025

SAP has released out-of-band patch to address CVE-2025-31324, a critical zero-day vulnerability in SAP NetWeaver that has been exploited by threat actors. Organizations are strongly encouraged to apply patches as soon as possible.BackgroundOn April 22, ReliaQuest published details of their investigation of exploit activity in SAP NetWeaver servers. Initially it was unclear if their discovery was a new vulnerability or the abuse of CVE-2017-9844, a vulnerability that could lead to a denial-of-service (DoS) condition or arbitrary code execution. ReliaQuest reported their findings to SAP and on April 24, SAP disclosed CVE-2025-31324, a critical missing authorization check vulnerability with the highest severity CVSS score of 10.0.CVEDescriptionCVSSv3VPRCVE-2025-31324SAP NetWeaver Unauthenticated File Upload Vulnerability10.08.1*Please note: Tenable’s Vulnerability Priority Rating (VPR) scores are calculated nightly.

Successful exploitation of this vulnerability could allow an unauthenticated attacker to upload malicious files which can be used by an attacker to achieve code execution. The flaw is the result of missing authorization checks to the “/developmentserver/metadatauploader” endpoint. According to ReliaQuest, this vulnerability has been exploited in the wild as a zero-day by threat actors who have abused the flaw to upload malicious web shells to affected hosts. These webshells were used to deploy malware and establish communications with command and control (C2) servers.Proof of conceptAt the time this blog was published, no proof-of-concept (PoC) code had been published for CVE-2025-31324. If a public PoC exploit becomes available, we anticipate a variety of attackers will attempt to leverage this flaw in their attacks as SAP products are…
