Attack Vector: Network
Attack Complexity: Low

Scope: Unchanged

Integrity: Low
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: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: None: There is no loss of confidentiality within the impacted component.
Integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 3 Jun 2025
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 1 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.

AI-suggested

Users should upgrade to the updated RHEL-8 based Middleware Containers container images available from the Red Hat Container Registry as per RHSA-2025:11386 and RHSA-2025:10698 advisories. It is also recommended to rebuild all container images that depend on these updated images to ensure the patches are fully applied. Dockerfiles and scripts should be updated to reference the new image versions. No additional mitigations are indicated by the vendor advisory.

Description

Red Hat has updated its RHEL-8 based Middleware Containers container images to address multiple security vulnerabilities, including several related to Python's tarfile extraction and libxml2 library. These updates include backported patches that fix issues such as directory traversal, arbitrary writes, heap use-after-free, type confusion, and buffer overflows. Users are advised to upgrade to the updated images and rebuild dependent container images to mitigate these security risks.

Impact

The vulnerabilities fixed include directory traversal and extraction filter bypasses that could allow modification or creation of files outside intended directories, arbitrary writes leading to potential code execution or corruption, heap use-after-free and type confusion in libxml2 causing denial of service, and a stack buffer overflow in libxml2 which could lead to memory corruption. These issues pose a high security risk to systems running affected container images, potentially allowing attackers to compromise container integrity or cause service disruption.

Summary

The RHEL-8 based Middleware Containers container images have been updated to fix multiple security vulnerabilities detailed in Red Hat Security Advisories RHSA-2025:11386 and RHSA-2025:10698. Key fixes include CVE-2024-12718 and CVE-2025-4138 which involve bypassing extraction filters to modify or link files outside the extraction directory, CVE-2025-4517 related to arbitrary writes via tarfile realpath overflow, and several libxml2 vulnerabilities (CVE-2025-49794, CVE-2025-49796, CVE-2025-6021) causing denial of service or stack buffer overflow. The advisory recommends upgrading container images from the Red Hat Container Registry and rebuilding all dependent images. These updates affect Red Hat OpenShift Container Platform versions 4.10 through 4.12 for RHEL 8 x86_64. The vendor advisory confirms these fixes and classifies the security impact as Important/High.

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).
