SAP has addressed 21 new vulnerabilities affecting its products, including three critical severity issues impacting the NetWeaver software solution.
SAP NetWeaver is the foundation for SAP's business apps like ERP, CRM, SRM, and SCM, and acts as a modular middleware that is broadly deployed in large enterprise networks.
In its security bulletin for September, the provider of enterprise resource planning (ERP) software lists a vulnerability with a maximum severity score of 10 out of 10 that is identified as CVE-2025-42944.
The security issue is an insecure deserialization vulnerability in SAP NetWeaver (RMIP4), ServerCore 7.50.
An unauthenticated attacker could exploit it to achieve arbitrary OS command execution by sending to an open port a malicious Java object through the RMI-P4 module.
RMI-P4 is the Remote Method Invocation protocol used by SAP NetWeaver AS Java for internal SAP-to-SAP communication, or for administration.
Though the P4 port is open on the host, some organizations may inadvertently expose it to wider networks, or the internet, due to firewall or other misconfigurations.
According to the security bulletin, the second critical flaw SAP fixed this month is CVE-2025-42922 (CVSS v3.1 score: 9.9), an insecure file operations bug impacting NetWeaver AS Java (Deploy Web Service), J2EE-APPS 7.50.
An attacker with non-administrative authenticated access can exploit a flaw in the web service deployment functionality to upload arbitrary files, potentially allowing full system compromise.
The third flaw is a missing authentication check in NetWeaver, tracked under CVE-2025-42958 (CVSS v3.1 score: 9.1).
This vulnerability allows unauthorized high-privileged users to read, modify, or delete sensitive data and access administrative functionality.
SAP also addressed the following new high-severity flaws:
CVE-2025-42933 (SAP Business One SLD): Insecure storage of sensitive data (e.g., credentials) that could be extracted and abused.
CVE-2025-42929 (SLT Replication Server): Missing input validation allowing malicious input to corrupt or manipulate replicated data.
CVE-2025-42916 (S/4HANA): Missing input validation in core components, risking unauthorized data manipulation.
SAP products, deployed by large organizations and often handling mission-critical data, are often targeted by threat actors seeking high-value compromises.
Earlier this month, it was revealed that hackers were exploiting a critical code injection vulnerability tracked as CVE-2025-42957, impacting S/4HANA, Business One, and NetWeaver products.
System administrators are recommended to follow the patching and mitigation recommendations for the three critical flaws, available here (1, 2, 3) for customers with a SAP account.
This blog post is a detailed write-up of one of the vulnerabilities we disclosed at Black Hat USA this year. The details provided in this post are meant to demonstrate how these security issues can manifest and be exploited in the hopes that others can avoid similar issues. This is not meant to shame any particular vendor; it happens to everyone. Security is a process, and avoiding vulnerabilities takes constant vigilance.
Note: The security issues documented in this post were quickly remediated in January of 2025. We appreciate CodeRabbit’s swift action after we reported this security vulnerability. They reported to us that within hours, they addressed the issue and strengthened their overall security measures responding with the following:
They confirmed the vulnerability and immediately began remediation, starting by disabling Rubocop until a fix was in place.
All potentially impacted credentials and secrets were rotated within hours.
A permanent fix was deployed to production, relocating Rubocop into their secure sandbox environment.
They carried out a full audit of their systems to ensure no other services were running outside of sandbox protections, automated sandbox enforcement to prevent recurrence, and added hardened deployment gates.

Be careful if you want to play Call of Duty: WW2 through Game Pass on PC – some users have been reporting falling victim to RCE (Remote Command Execution) hacks. The earliest reports of this surfaced just a few hours ago, with players taking to social media to share some concerning stories, while others stressed this has been a problem ‘for years’ in COD WW2.
Hackers are actively exploiting CVE-2025-49113, a critical vulnerability in the widely used Roundcube open-source webmail application that allows remote execution.
The security issue has been present in Roundcube for over a decade and impacts versions of Roundcube webmail 1.1.0 through 1.6.10. It received a patch on June 1st.
It took attackers just a couple of days to reverse engineer the fix, weaponize the vulnerability, and start selling a working exploit on at least one hacker forum.
Roundcube is one of the most popular webmail solutions as the product is included in offers from well-known hosting providers such as GoDaddy, Hostinger, Dreamhost, or OVH.
"Email armageddon"
CVE-2025-49113 is a post-authentication remote code execution (RCE) vulnerability that received a critical severity score of 9.9 out of 10 and is described as “email armageddon.”
It was discovered and reported by Kirill Firsov, the CEO of the cybersecurity company FearsOff, who decided to publish the technical details before the end of the responsible disclosure period because an exploit had become available.
On May 13, 2025, FortiGuard Labs published an advisory detailing CVE-2025-32756, which affects a variety of Fortinet products:
FortiCamera
FortiMail
FortiNDR
FortiRecorder
FortiVoice
In their advisory, FortiGuard Labs states that Fortinet has observed this issue being exploited in the wild. The next day, May 14, the vulnerability was added to the CISA KEV catalog.
The vulnerability is described in the advisory as a stack-based buffer overflow in the administrative API that can lead to unauthenticated remote code execution. Given that it’s being exploited in the wild, we figured we’d take a closer look. If you’d rather run the test instead of reading this write-up, coverage is already available in NodeZero.
Critical vulnerabilities in Versa Concerto that are still unpatched could allow remote attackers to bypass authentication and execute arbitrary code on affected systems.
Three security issues, two of them critical, were publicly disclosed by researchers at the vulnerability management firm ProjectDiscovery after reporting them to the vendor and receiving no confirmation of the bugs being addressed.
Versa Concerto is the centralized management and orchestration platform for Versa Networks' SD-WAN and SASE (Secure Access Service Edge) solutions.

Keeping your ears to the ground and eyes wide open for the latest vulnerability news at watchTowr is a given. Despite rummaging through enterprise code looking for 0days on a daily basis, our interest was piqued this week when news of fresh vulnerabilities was announced in a close friend - Ivanti, and their Endpoint Manager Mobile (Ivanti EPMM) solution.
For those out of the loop, don’t worry - as always, we’re here to fill you in.
Ivanti Endpoint Manager Mobile (EPMM) is an MDM solution for system administrators to install and manage devices within an organization. It hopes to prevent you from installing malware or enjoying your life by watching YouTube during any permitted and sanctioned downtime.
Why Is This Important?
Well, short of their intended functionality, MDM solutions are, in a sense, C2 frameworks for enterprises… allowing system administrators to manage software on their devices.
Picture this: You’ve compromised the MDM solution at one of the largest banks and are able to deploy malicious software at scale to employee devices.
And it's Friday!
In April 2024, I discovered a high-severity vulnerability in Visual Studio Code (VS Code <= 1.89.1) that allows attackers to escalate a Cross-Site Scripting (XSS) bug into full Remote Code Execution (RCE)—even in Restricted Mode.
The desktop version of Visual Studio Code runs on Electron. Renderer processes are sandboxed and communicate with the main process through Electron’s IPC mechanism.
An XSS vulnerability in the newly-introduced minimal error rendering mode for Jupyter notebooks enables arbitrary JavaScript code to be executed within the vscode-app WebView for the notebook renderer. The vulnerability can be triggered by opening a crafted .ipynb file if the user has the setting enabled, or by opening a folder containing a crafted settings.json file in VS Code and opening a malicious ipynb file within the folder. This vulnerability can be triggered even when Restricted Mode is enabled (which is the default for workspaces that have not been explicitly trusted by the user).
In this post, we’ll walk through how the bug works and how it bypasses VS Code’s Restricted Mode.
