CVE-2023-22399 (GCVE-0-2023-22399)

Vulnerability from cvelistv5 – Published: 2023-01-12 00:00 – Updated: 2025-04-07 15:39

Title

Junos OS: QFX10K Series: PFE crash upon receipt of specific genuine packets when sFlow is enabled

Summary

When sFlow is enabled and it monitors a packet forwarded via ECMP, a buffer management vulnerability in the dcpfe process of Juniper Networks Junos OS on QFX10K Series systems allows an attacker to cause the Packet Forwarding Engine (PFE) to crash and restart by sending specific genuine packets to the device, resulting in a Denial of Service (DoS) condition. The dcpfe process tries to copy more data into a smaller buffer, which overflows and corrupts the buffer, causing a crash of the dcpfe process. Continued receipt and processing of these packets will create a sustained Denial of Service (DoS) condition. This issue affects Juniper Networks Junos OS on QFX10K Series: All versions prior to 19.4R3-S9; 20.2 versions prior to 20.2R3-S6; 20.3 versions prior to 20.3R3-S6; 20.4 versions prior to 20.4R3-S5; 21.1 versions prior to 21.1R3-S4; 21.2 versions prior to 21.2R3-S3; 21.3 versions prior to 21.3R3-S2; 21.4 versions prior to 21.4R2-S2, 21.4R3; 22.1 versions prior to 22.1R2; 22.2 versions prior to 22.2R1-S2, 22.2R2.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.

Vulnerabilities whose description is nearest to this one in the vector space of the CIRCL/vulnerability-attack-technique-biencoder model. This is a similarity search over the bi-encoder space (plain cosine), not a classification, and it has no measured accuracy.
