A severe security vulnerability has just been uncovered in SAP NetWeaver, demanding immediate attention from businesses worldwide. SAP has released an emergency out-of-band patch to address CVE-2025-31324, a critical zero-day flaw within the SAP NetWeaver Visual Composer. This vulnerability carries the absolute highest severity score on the Common Vulnerability Scoring System (CVSS): a perfect 10.0!

Why is this such a big deal? The problem is that there is a lack of authorization verification in the Metadata Uploader section of the Visual Composer. Through this, unauthorized attackers who never even authenticated their identities can load malicious executable content onto compromised systems. All an attacker needs to do is submit a specially prepared POST request to the /developmentserver/metadatauploader endpoint.

Alarmingly, ReliaQuest, Rapid7, and Onapsis security experts have verified that this vulnerability is already actively exploited in the wild. Indications are that these attacks have been in effect since as far back as March 2025, so systems may already be infested.

The active exploitation was discovered by ReliaQuest in their forensic analysis of SAP environments that were compromised. ReliaQuest notified SAP immediately, which resulted in the quick validation and deployment of the emergency patch.

Now, here’s an important fact to know: although the SAP NetWeaver Visual Composer component is not installed automatically in a typical NetWeaver installation, it’s said by Onapsis to be “broadly enabled.” Why? Because it was traditionally a major tool for business process experts. It enabled users who lacked coding skills to create business application components through a simple visual, drag-and-drop interface. This simplicity probably helped make it so widely used.

What does it mean to you? If your company uses SAP NetWeaver, even though you may not be actively utilizing the Visual Composer, it’s crucial to ensure that the component is activated. If it is, installing the emergency patch SAP has made available should be your top priority to avoid possible system compromise.

Keeping Your Digital Assets Safe: Cybersecurity Expertise
In the fast-changing threat environment of today, it is essential to stay ahead of vulnerabilities such as this SAP NetWeaver vulnerability. This case highlights the urgent necessity for strong cybersecurity measures and experts who can detect, neutralize, and prevent such attacks.

Talking about expertise, if you’re planning to develop a solid cybersecurity foundation, especially in Kerala, there’s one place that shines: Coreframe.

Coreframe is a well-known institution for cybersecurity training in Kerala. They provide full-fledged training programs that are intended to enable students with the appropriate knowledge and skills required to address contemporary cyber threats. Their courses are frequently created with emphasis on industry context so that students are adequately equipped to handle the realities of the cybersecurity world. Whether you’re an aspiring cybersecurity professional or a working professional wanting to upskill, Coreframe offers a robust learning environment and useful industry networking. Their emphasis on practical training and real-world applications can prove to be a major plus in this fast-evolving field.

Finally, the SAP NetWeaver zero-day vulnerability is a stark reminder of the constant watchfulness in cybersecurity. Make sure you’re taking urgent steps to patch your systems if impacted, and make an investment in strong cybersecurity expertise and know-how – organizations such as Coreframe in Kerala have a key role to play in creating a secure digital future.
