Red Hat Security Advisory: iscsi-initiator-utils security update

Severity

Important

Scope

2 vulnerabilities in this advisory, including CVE-2026-44943.

CVE-2026-44943

A flaw was found in open-iscsi. This vulnerability, known as Path Traversal, allows remote Man-in-the-Middle (MITM) attackers to manipulate file paths. By doing so, attackers can create files with root privileges outside the intended database and inject malicious content into system records. This could lead to unauthorized system modification or privilege escalation.

8.6 (High)


                
                  CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:H/A:N

Summary

Important: iscsi-initiator-utils security, bug fix, and enhancement update

Details

The iscsi-initiator-utils packages provide the server daemon for the Internet Small Computer System Interface (iSCSI) protocol, as well as the utility programs used to manage it. The iSCSI protocol is a protocol for distributed disk access using SCSI commands sent over Internet Protocol (IP) networks.

Security Fix(es):

open-iscsi: open-iscsi: Authentication bypass in iscsiuio control socket (CVE-2026-44944)
open-iscsi: open-iscsi: Privilege Escalation via Path Traversal (CVE-2026-44943)

Bug Fix(es) and Enhancement(s):

[FJ9.7 Bug][REG]: iscsiadm reports node.discovery_type as "fw", although it should be "static". [rhel-9.8.z] (JIRA:Rocky Linux-191897)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

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.
