Linux vulnerabilities pose significant risks, particularly CVE 20258067, which has active exploits in rebased distributions. CVE 202332256 enables remote attackers to access sensitive information without authentication. Additionally, CVE 202558367 presents a denial of service and remote code execution risk in the Delta class. Applications handling untrusted user input to Delta need careful scrutiny, and it is crucial to keep systems updated to mitigate these threats.
Microsoft addresses 81 CVEs in its latest Patch Tuesday updates, including a significant third-party vulnerability in SQL Server. An important Windows SMB vulnerability is also disclosed, though it lacks exploit code. The focus shifts towards exposure management, emphasizing risk appetite and automation in updates. Proactive maintenance configurations are recommended to mitigate vulnerabilities, highlighting the need for regular maintenance and proactive security measures.
AI technologies are advancing, improving content generation and analysis. Generative AI helps summarize information quickly, especially during updates like Patch Tuesday. However, these models have limitations, including errors in information retrieval. Threat actors are using AI for complex attacks, leading to a rise in zero-day exploits. Transitioning to SaaS applications is essential for better security, as on-premises solutions are more vulnerable.
A zero day vulnerability in WIN RAR is being actively exploited by multiple threat actors, including the first identified actor, Romcom. It is essential to address the related CVEs to mitigate risks. Recent details about a critical bug and recommended versions for resolution are provided. Additionally, there are discussions about exploits related to WhatsApp.
Key Takeaways
The majority of risks this month occurred leading up to Patch Tuesday, with zero-day vulnerabilities in Android (CVE-2025-38352, CVE-2025-48543), WhatsApp (CVE-2025-55177) and WinRAR (CVE-2025-8088).
Microsoft resolved 81 new CVEs, including two public disclosures. Eight CVEs are rated Critical by Microsoft (five RCE, two Elevation of Privilege, one Information Disclosure) and affect the Windows OS and Office.
Adobe released nine updates addressing 22 CVEs. Adobe has rated the ColdFusion update as a priority one and Commerce as a priority two.
The days leading into September Patch Tuesday include a bit of chaos from a pair of actively exploited Android CVEs (CVE-2025-38352, CVE-2025-48543), a zero day in WhatsApp (CVE-2025-55177), another zero day in WinRAR (CVE-2025-8088), and a major supply chain attack through the Drift AI Chat Agent exposing Salesforce customers data.
The good news is Microsoft only has a pair of publicly disclosed vulnerabilities (CVE-2025-55234, CVE-2024-21907) out of 81 total CVEs resolved this month, making this about as close to a calm Patch Tuesday as we can hope for.
The Windows OS and Office updates are rated Critical this month, putting those as the highest priority, but with no zero-day exploits, this month should be focused on routine maintenance from a Microsoft perspective.
Microsoft’s publicly disclosed vulnerabilities
Microsoft has resolved an Elevation of Privilege vulnerability in Windows SMB (CVE-2025-55234), which Microsoft has confirmed is publicly disclosed. Microsoft rates the CVE as Important, and it has a CVSS v3.1 score of 8.8 and affects all Windows OS editions. The code maturity is unproven, which would indicate no code samples have been disclosed. A risk-based prioritization methodology would warrant treating this as Important.
Microsoft has resolved an Improper Handling of Exceptional Conditions vulnerability in Newtonsoft.Json (CVE-2024-21907), which Microsoft has confirmed is publicly disclosed. The CVE is unrated and affects SQL Server 2016, 2017 and 2019. Depending on the usage of the library, an unauthenticated and remote attacker may be able to cause the denial-of-service condition. A risk-based prioritization methodology would warrant treating this as Important.
Third-party vulnerabilities
Adobe has released nine updates resolving 22 CVEs, 12 of which are rated Critical. The products affected include Adobe Acrobat Reader, After Effects, Premiere Pro, Commerce, Substance 3D Viewer, Experience Manager, Dreamweaver, 3D Substance Modeler and ColdFusion. Adobe has rated the ColdFusion update as a priority one and Commerce as a priority two. The other seven updates are rated priority three.
