Availability: None

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
Confidentiality: None: There is no loss of confidentiality within the impacted component.
Integrity: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 25 Nov 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: 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

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 26 Oct 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.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, 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.

AI-suggested

Red Hat advises avoiding use of the glob CLI with the -c/--cmd option on untrusted filenames to mitigate the command injection vulnerability. Filenames should be sanitized before being passed to commands executed with shell interpretation enabled. Kiali 2.4.11 includes the fixes for these vulnerabilities. Users should upgrade to this version and follow the official Red Hat OpenShift Service Mesh 3.0 documentation for deployment and update instructions. Since this is not a cloud service, remediation is managed by the user applying the updated Kiali version. Monitor Red Hat advisories for any further updates or patches.

Description

Kiali 2.4.11, for Red Hat OpenShift Service Mesh 3.0, provides observability for the service mesh by offering a visual representation of the mesh topology and metrics, helping users monitor, trace, and manage efficiently Security Fix(es): * kiali-ossmc-rhel9: node-forge ASN.1 Unbounded Recursion (CVE-2025-66031) * kiali-rhel9: node-forge ASN.1 Unbounded Recursion (CVE-2025-66031) * kiali-ossmc-rhel9: glob CLI: Command injection via -c/--cmd executes matches with shell:true (CVE-2025-64756) * kiali-rhel9: glob CLI: Command injection via -c/--cmd executes matches with shell:true (CVE-2025-64756)

Impact

Successful exploitation of CVE-2025-64756 could allow an attacker to execute arbitrary operating system commands with the privileges of the Kiali process by leveraging command injection via malicious filenames processed by the glob CLI. CVE-2025-66031 could cause denial of service through unbounded recursion in ASN.1 parsing. These impacts include unauthorized code execution, potential data modification or disclosure, and service disruption. However, exploitation requires specific conditions such as the use of the vulnerable CLI with crafted filenames and appropriate permissions. There are no known exploits in the wild at this time.

Summary

The advisory for Kiali 2.4.11 in Red Hat OpenShift Service Mesh 3.0 reports fixes for three CVEs: CVE-2025-64756, CVE-2025-66031, and CVE-2025-12816. CVE-2025-64756 is a command injection vulnerability in the glob CLI when using the -c/--cmd option with shell:true, allowing execution of arbitrary OS commands via malicious filenames. CVE-2025-66031 involves an unbounded recursion issue in the node-forge ASN.1 parser, which can lead to denial of service. The vulnerabilities affect the command line interface components used by Kiali but not the programmatic use of glob in npm. The advisory does not explicitly state a patch release beyond Kiali 2.4.11, which includes these fixes. The vulnerabilities require conditions such as processing malicious filenames or having permissions to create such files. Red Hat rates the severity as high and provides guidance to avoid using vulnerable CLI options with untrusted input.

CWE-179Incorrect Behavior Order: Early Validation (opens in a new tab)
Base weakness
The product validates input before applying protection mechanisms that modify the input, which could allow an attacker to bypass the validation via dangerous inputs that only arise after the modification.
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).

Base weaknessLikelihood of exploit: HighCWE Top 25 (2025): #9OWASP Top 10 A05:2025: Injection (opens in a new tab)
The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component.
Architecture and Design
If at all possible, use library calls rather than external processes to recreate the desired functionality.
Architecture and Design · Operation · Sandbox or Jail
Run the code in a "jail" or similar sandbox environment that enforces strict boundaries between the process and the operating system. This may effectively restrict which files can be accessed in a particular directory or which commands can be executed by the software.
Architecture and Design · Attack Surface Reduction
For any data that will be used to generate a command to be executed, keep as much of that data out of external control as possible. For example, in web applications, this may require storing the data locally in the session's state instead of sending it out to the client in a hidden form field.

CWE-674Uncontrolled Recursion (opens in a new tab)
Class weakness
The product does not properly control the amount of recursion that takes place, consuming excessive resources, such as allocated memory or the program stack.
Implementation
Ensure that an end condition will be reached under all logic conditions. The end condition may include checking against the depth of recursion and exiting with an error if the recursion goes too deep. The complexity of the end condition contributes to the effectiveness of this action.
Implementation
Increase the stack size.
