In what's the latest evolution of threat actors abusing legitimate infrastructure for nefarious ends, new findings show that nation-state hacking groups have entered the fray in leveraging the social platform for targeting critical infrastructure. Discord, in recent years, has become a lucrative target, acting as a fertile ground for hosting malware using its content delivery network (CDN) as

Two critical security flaws discovered in the open-source CasaOS personal cloud software could be successfully exploited by attackers to achieve arbitrary code execution and take over susceptible systems. The vulnerabilities, tracked as CVE-2023-37265 and CVE-2023-37266, both carry a CVSS score of 9.8 out of a maximum of 10. Sonar security researcher Thomas Chauchefoin, who discovered the bugs,

An issue in YeaLinkSIP-T19P-E2 v.53.84.0.15 allows a remote privileged attacker to execute arbitrary code via a crafted request the ping function of the diagnostic component.

### Impact An attacker could use a recursive graphql query to execute a Distributed Denial of Service attack (DDOS attack) against a website. This mostly affects websites with publicly exposed graphql schemas. If your Silverstripe CMS project does not expose a public facing graphql schema, a user account is required to trigger the DDOS attack. If your site is hosted behind a content delivery network (CDN), such as Imperva or CloudFlare, this may further mitigate the risk. The fix includes some new configuration options which you might want to tweak for your project, based on your own requirements. See the documentation in the references for details. ### Patches Patched in [3.8.2](https://github.com/silverstripe/silverstripe-graphql/releases/tag/3.8.2), [4.1.3](https://github.com/silverstripe/silverstripe-graphql/releases/tag/4.1.3), [4.2.5](https://github.com/silverstripe/silverstripe-graphql/releases/tag/4.2.5), [4.3.4](https://github.com/silverstripe/silverstripe-graphql/releases/...

Improper signature counter value handling ### Impact A flaw was found in webauthn4j-spring-security-core. When an authneticator returns an incremented signature counter value during authentication, webauthn4j-spring-security-core does not properly persist the value, which means cloned authenticator detection does not work. An attacker who cloned valid authenticator in some way can use the cloned authenticator without being detected. ### Patches Please upgrade to `com.webauthn4j:webauthn4j-spring-security-core:0.9.1.RELEASE` ### References For more details about WebAuthn signature counters, see [WebAuthn specification 6.1.1. Signature Counter Considerations](https://www.w3.org/TR/2021/REC-webauthn-2-20210408/#sctn-sign-counter). ### Reporter This issue was discovered by Michael Budnick (@mbudnick)
