Pion DTLS uses random nonce generation with AES GCM ciphers risks leaking the authentication key

Exploitation and risk

CISA KEV lists vulnerabilities known to be exploited. FIRST EPSS estimates the likelihood of exploitation in the next 30 days. An unavailable score does not mean zero risk.

Which CVEs have scores here?

This view includes predictions for CVE identifiers explicitly listed in public NuGet advisories. Microsoft release pages have their own prediction coverage. Check source status for the scope and latest checks.

No exploitation or prediction data is available here for these CVEs. This does not mean they are safe or unlikely to be exploited.

Published

Pion DTLS is a Go implementation of Datagram Transport Layer Security. Pion DTLS versions v1.0.0 through v3.0.10 and 3.1.0 use random nonce generation with AES GCM ciphers, which makes it easier for remote attackers to obtain the authentication key and spoof data by leveraging the reuse of a nonce in a session and a "forbidden attack". Upgrade to v3.0.11, v3.1.1, or later.

### Impact Pion DTLS versions v1.0.0 through v3.0.10 use random nonce generation with AES GCM ciphers, which makes it easier for remote attackers to obtain the authentication key and spoof data by leveraging the reuse of a nonce in a session and a "forbidden attack". ### Patches Upgrade to v3.1.1 or later. This version includes PR #796, which uses the 64-bit sequence number to populate the `nonce_explicit` part of the GCM nonce. This is according to best practice outlined in [RFC 9325 section 7.2.1](https://www.rfc-editor.org/rfc/rfc9325#section-7.2.1). v3.0.11 is a backport patch supporting Go v1.21 ### Workarounds There are no workarounds without upgrading to version v3.0.11, v3.1.1 or later. ### References Commit fixing the bug: https://github.com/pion/dtls/commit/61762dee8217991882c5eb79856b9e7a73ee349f Commit fixing the bug (backport): 90e241c Pull request: #796
