Threat & Defense Details
Likely Mitigating ControlsAI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
This control implements explicit throttling on session allocation, addressing the weakness of allocating resources without limits.
Plan testing exercises resource allocation limits and throttling during simulated failures, directly addressing weaknesses that allow unbounded resource use.
Contingency plan updates ensure recovery strategies address unbounded resource allocation, making it harder for attackers to exploit lack of throttling to cause prolonged outages.
Provides continuity when unbounded resource allocation at the primary site leads to exhaustion and downtime.
Alternate services allow operations to continue when primary allocation of resources lacks limits or throttling.
Explicit planning of security-related actions requires defining limits, windows, and resource allocations, making allocation without throttling far less likely.
Measures of performance include tracking allocation behavior and throttling effectiveness, reducing the window for resource exhaustion attacks.
Imposes an inactivity-based limit on network resource allocation, throttling the number of concurrently held connections.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
DoS via trap on SELECT directly matches application exploitation for endpoint denial of service.
NVD Description
IBM Db2 for Linux, UNIX and Windows (includes Db2 Connect Server) 11.5.0 - 11.5.9 and 12.1.0 - 12.1.3 is vulnerable to a denial of service as a trap may occur when selecting from certain types of tables.
Deeper analysisAI
CVE-2025-36070 is a denial-of-service vulnerability (CWE-770) in IBM Db2 for Linux, UNIX, and Windows, including Db2 Connect Server, affecting versions 11.5.0 through 11.5.9 and 12.1.0 through 12.1.3. The issue occurs when a trap is triggered during SELECT operations on certain types of tables, with a CVSS v3.1 base score of 6.5 (AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H).
An authenticated attacker with low privileges can exploit this vulnerability remotely over the network with low complexity and no user interaction. Exploitation triggers a trap that results in high-impact denial of service by disrupting database availability, without compromising confidentiality or integrity.
