Vulnerability Data

Undisclosed requests can cause the Traffic Management Microkernel (TMM) to terminate. For the Application Visibility and Reporting module, this may occur when the HTTP Analytics profile with URLs enabled under Collected Entities is configured on a virtual server and the…

DB variables avr.IncludeServerInURI or avr.CollectOnlyHostnameFromURI are enabled. For BIG-IP Advanced WAF and ASM, this may occur when either a DoS or Bot Defense profile is configured on a virtual server and the DB variables avr.IncludeServerInURI or avr.CollectOnlyHostnameFromURI are enabled. Note: The DB variables avr.IncludeServerInURI and avr.CollectOnlyHostnameFromURI are not enabled by default. For more information about the HTTP Analytics profile and the Collect URLs setting, refer to K30875743: Create a new Analytics profile and attach it to your virtual servers https://my.f5.com/manage/s/article/K30875743 . Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer security testing and code review can discover incorrect buffer-size computations before deployment.

SA-8 Security and Privacy Engineering Principles partial match

Secure engineering principles directly require correct buffer-size arithmetic and bounds-checked allocation.

SI-10 Information Input Validation partial match

Input validation can enforce that supplied lengths or counts used in size calculations are within safe bounds.

SI-16 Memory Protection partial match

Memory-protection mechanisms limit the exploitability of an overflow that results from an incorrect size calculation.

SI-2 Flaw Remediation partial match

Flaw-remediation processes that include vulnerability scanning or static analysis will surface buffer-size errors.

PR.PS-06 mostly match

prevents

Secure SDLC practices directly prevent buffer-size miscalculations via coding standards, reviews, and testing, while fixing this single weakness only partially fulfills the broader control.
