CVE-2024-39515 Details
An Improper Validation of Consistency within Input vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated network-based attacker sending a specifically malformed BGP packet to cause rpd to crash and restart, resulting in a Denial of Service (DoS). Continued receipt and processing of this packet will create a sustained Denial of Service (DoS) condition.

In some cases, rpd fails to restart requiring a manual restart via the 'restart routing' CLI command.

This issue only affects systems with BGP traceoptions enabled and

requires a BGP session to be already established. Systems without BGP traceoptions enabled are not affected by this issue.

This issue affects iBGP and eBGP, and both IPv4 and IPv6 are affected by this vulnerability.

This issue affects:

Junos OS: 

* All versions before 21.4R3-S8, 
* 22.2 before 22.2R3-S5, 
* 22.3 before 22.3R3-S4, 
* 22.4 before 22.4R3-S3, 
* 23.2 before 23.2R2-S2, 
* 23.4 before 23.4R2; 


Junos OS Evolved: 

* All versions before 21.4R3-S8-EVO, 
* 22.2-EVO before 22.2R3-S5-EVO, 
* 22.3-EVO before 22.3R3-S4-EVO, 
* 22.4-EVO before 22.4R3-S3-EVO, 
* 23.2-EVO before 23.2R2-S2-EVO, 
* 23.4-EVO before 23.4R2-EVO.

Exploit prediction scoring system (EPSS) score for CVE-2024-39515
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%).
0.28 Probability of exploitation activity being observed over the next 30 days (51st percentile)
CVSS score for CVE-2024-39515
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.
