Exploitation evidence

Disclosed: evidence found.
CVE published 1 Sep 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponized: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 5 Nov 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

What to do

AI-suggested

Red Hat has released updated iscsi-initiator-utils packages that address these vulnerabilities. Users of Red Hat Enterprise Linux 9.2 and related variants should apply the security update as detailed in Red Hat advisory RHSA-2026:62029 and the referenced article https://access.redhat.com/articles/11258. Applying this update will remediate the authentication bypass and privilege escalation issues. No additional mitigation steps are indicated by the vendor advisory.

Description

Red Hat has issued a security advisory for iscsi-initiator-utils addressing two vulnerabilities in the open-iscsi component: an authentication bypass in the iscsiuio control socket (CVE-2026-44944) and a privilege escalation via path traversal (CVE-2026-44943). These vulnerabilities affect the iscsi-initiator-utils packages used for managing the iSCSI protocol, which facilitates distributed disk access over IP networks. The update is rated as having an Important security impact by Red Hat and is available for Red Hat Enterprise Linux 9.2 and related variants.

Impact

Successful exploitation of CVE-2026-44944 could allow an attacker to bypass authentication controls in the iscsiuio control socket, potentially leading to unauthorized actions. CVE-2026-44943 could enable privilege escalation through a path traversal vulnerability, allowing an attacker to gain higher privileges on the affected system. Both vulnerabilities affect the iscsi-initiator-utils packages used in Red Hat Enterprise Linux 9.2 and related variants. The security impact is rated as Important by Red Hat, indicating a significant risk if unpatched.

Summary

The iscsi-initiator-utils packages provide the server daemon and utilities for the iSCSI protocol. Two security issues have been fixed: CVE-2026-44944 involves an authentication bypass vulnerability in the iscsiuio control socket, potentially allowing unauthorized access. CVE-2026-44943 is a privilege escalation vulnerability via path traversal in open-iscsi, which could allow an attacker to gain elevated privileges. Red Hat has released updates for these vulnerabilities in iscsi-initiator-utils for Red Hat Enterprise Linux 9.2 and related distributions. The advisory references detailed CVE pages for further information.

CWE-22Improper Limitation of a Pathname to a Restricted Directory (Path Traversal) (opens in a new tab)
Base weaknessLikelihood of exploit: HighCWE Top 25 (2025): #6OWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
Implementation · Input Validation
Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
Architecture and Design
For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks…
Implementation · Input Validation
Inputs should be decoded and canonicalized to the application's current internal representation before being validated (CWE-180). Make sure that the application does not decode the same input twice (CWE-174).

CWE-1220Insufficient Granularity of Access Control (opens in a new tab)
Base weakness
The product implements access controls via a policy or other feature with the intention to disable or restrict accesses (reads and/or writes) to assets in a system from untrusted agents. However, implemented access controls lack the required granularity
Architecture and Design · Implementation · Testing
Access-control-policy protections must be reviewed for design inconsistency and common weaknesses.; Access-control-policy definition and programming flow must be tested in pre-silicon, post-silicon testing.
