Vulnerability from github – Published: 2025-11-20 15:30 – Updated: 2025-11-21 21:30
VLAI
Details

Vulnerability in LimeSurvey 6.13.0 in the endpoint /optout that causes infinite HTTP redirects when accessed directly. This behavior can be exploited to generate a Denegation of Service (DoS attack), by exhausting server or client resources. The system is unable to break the redirect loop, which can cause service degradation or browser instability.

GHSA-2P3X-QW9C-25HH

Vulnerability from github – Published: 2021-03-22 23:27 – Updated: 2022-02-08 21:33
VLAI
Summary
XStream can cause a Denial of Service.
Details

Impact

The vulnerability may allow a remote attacker to allocate 100% CPU time on the target system depending on CPU type or parallel execution of such a payload resulting in a denial of service only by manipulating the processed input stream. No user is affected, who followed the recommendation to setup XStream's security framework with a whitelist limited to the minimal required types.

Patches

If you rely on XStream's default blacklist of the Security Framework, you will have to use at least version 1.4.16.

Workarounds

See workarounds for the different versions covering all CVEs.

References

See full information about the nature of the vulnerability and the steps to reproduce it in XStream's documentation for CVE-2021-21341.

Credits

Vulnerability from github – Published: 2022-05-24 19:01 – Updated: 2022-05-24 19:01
VLAI
Details

On BIG-IP version 16.0.x before 16.0.1.1 and 15.1.x before 15.1.3, malformed HTTP/2 requests may cause an infinite loop which causes a Denial of Service for Data Plane traffic. TMM takes the configured HA action when the TMM process is aborted. There is no control plane exposure, this is a data plane issue only. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

The web server of affected products, if configured to allow the import of PKCS12 containers, could end up in an infinite loop when processing incomplete certificate chains.

This could allow an authenticated remote attacker to create a denial of service condition by importing specially crafted PKCS12 containers.
