IBM DB2, QRadar, Sterling Connect:Direct vulnerabilities
Free public brief. The indicators, the detections with Splunk SPL already written (plus Elastic and KQL where they apply), and a Slack alert the next time this touches a vendor you run are in the app — free account, no card.
Multiple vulnerabilities in IBM database, SIEM and file-transfer products allow remote code execution and denial of service.
CERT-FR has published a security advisory covering multiple vulnerabilities across four IBM product lines. DB2 Query Management Facility for z/OS (versions 12.2.0.5, 13.1.x, 13.1.1, 13.1.2, 13.1.3), QRadar SIEM (7.5.x before 7.5.0 UP16 and 7.6.x before 7.6.0 FP3), and Sterling Connect:Direct for Microsoft Windows (6.3.x before 6.3.0.6_iFix076 and 6.4.x before 6.4.0.5_iFix012) are all affected.
The vulnerabilities enable attackers to achieve remote code execution, remote denial of service, data integrity compromise, and security policy bypass. Defenders running these products in their infrastructure—particularly those using QRadar for security monitoring or DB2 for mainframe database operations—should treat patching as urgent. The advisory references 40 CVE identifiers and directs administrators to IBM's security bulletins for specific patches corresponding to each affected product version.

What this brief leaves out
This page is the free tier: the write-up, the severity, the names. In the app the same report carries its extracted indicators, its detections (Splunk SPL already written, plus Elastic and Microsoft KQL where they apply), the actors and CVEs it names as live profiles, and the vendor research on the same campaign — the primary source the news paraphrased, cited and read directly.
It sits in a corpus of 13,854 reports from 146 sources, 616 of them written in the last seven days, and it grows through the day.
A new account starts with three days of all of it, no card, then keeps the government and CERT reporting free. Name the vendors you run and Slack hears about the reports that touch them — about forty a week that are yours, not the four hundred that are not.
