CVE-2024-12797 Details
Issue summary: Clients using RFC7250 Raw Public Keys (RPKs) to authenticate a
server may fail to notice that the server was not authenticated, because
handshakes don't abort as expected when the SSL_VERIFY_PEER verification mode
is set.

Impact summary: TLS and DTLS connections using raw public keys may be
vulnerable to man-in-middle attacks when server authentication failure is not
detected by clients.

RPKs are disabled by default in both TLS clients and TLS servers. The issue
only arises when TLS clients explicitly enable RPK use by the server, and the
server, likewise, enables sending of an RPK instead of an X.509 certificate
chain. The affected clients are those that then rely on the handshake to
fail when the server's RPK fails to match one of the expected public keys,
by setting the verification mode to SSL_VERIFY_PEER.

Clients that enable server-side raw public keys can still find out that raw
public key verification failed by calling SSL_get_verify_result(), and those
that do, and take appropriate action, are not affected. This issue was
introduced in the initial implementation of RPK support in OpenSSL 3.2.

The FIPS modules in 3.4, 3.3, 3.2, 3.1 and 3.0 are not affected by this issue.

Exploit prediction scoring system (EPSS) score for CVE-2024-12797
EPSS (Exploit Prediction Scoring System): EPSS predicts the likelihood that a vulnerability will be exploited in the wild. A higher percentage means a greater chance of an exploit occurring. The EPSS model produces a probability score between 0 and 1 (0 and 100%).
1.92 Probability of exploitation activity being observed over the next 30 days (80th percentile)
CVSS score for CVE-2024-12797
CVSS (Common Vulnerability Scoring System): An open framework owned and managed by FIRST.Org, Inc. that assigns a numerical score from 0 to 10 to software vulnerabilities to indicate their severity.

Bitsight Data Discovery and Continuous Threat Scanning

Bitsight, the leading provider in Cyber Risk Management, introduced the next-generation internet scanner Bitsight Groma in May 2024. This technology continuously scans the entire internet to discover assets, collect asset attribution evidence, and identify an ever-growing set of security observations, such as vulnerabilities and misconfigurations. Groma’s scanning activities presently encompass:


  • 40 million-plus monitored organizations
  • 250 million-plus host names
  • 4 billion-plus routable IPv4 and IPv6 addresses

Greynoise’s recent study testifies the speed of Bitsight Groma.
