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

Attack Vector: Network: The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, 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: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: None: The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required: Low: The attacker requires privileges that provide basic capabilities that are typically limited to settings and resources owned by a single low-privileged user. Alternatively, an attacker with Low privileges has the ability to access only non-sensitive resources.
User Interaction: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable system confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the Vulnerable System.
Vulnerable system 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 to the Vulnerable System.
Vulnerable system availability: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the Vulnerable System are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the Vulnerable System.
Subsequent system confidentiality: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable System.
Subsequent system integrity: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.

Exploitation evidence

Disclosed: evidence found.
CVE published 16 Oct 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
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 2026-10-25.

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 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

To mitigate CVE-2025-11842, European organizations should immediately upgrade Shazwazza Smidge to version 4.6.0 or later, as this update contains the necessary fixes. In addition to patching, organizations should implement strict input validation and sanitization on all parameters, especially those influencing file paths, to prevent path traversal attempts. Employing web application firewalls (WAFs) with rules to detect and block path traversal patterns can provide an additional layer of defense. Conduct thorough code reviews and security testing on web asset management components to identify similar vulnerabilities proactively. Limit the privileges of the application process running Smidge to the minimum necessary, restricting file system access to only required directories. Monitor logs for unusual file access patterns or errors related to the Bundle Handler component. Finally, maintain an up-to-date inventory of software components and their versions to ensure timely patch management and vulnerability response.

Description

A security vulnerability has been detected in Shazwazza Smidge up to 4.5.1. The impacted element is an unknown function of the component Bundle Handler. The manipulation of the argument Version leads to path traversal. Remote exploitation of the attack is possible. Upgrading to version 4.6.0 is sufficient to resolve this issue. It is recommended to upgrade the affected component.

Impact

For European organizations, the impact of CVE-2025-11842 can be significant, especially for those relying on Shazwazza Smidge for web asset management in their .NET web applications. Exploitation could lead to unauthorized access to sensitive configuration files, source code, or other critical data, potentially exposing intellectual property or user data. This could result in data breaches, compliance violations (e.g., GDPR), and reputational damage. Additionally, attackers might modify or delete assets, causing service disruption or defacement of websites, impacting business continuity and customer trust. Organizations in sectors with stringent data protection requirements, such as finance, healthcare, and government, are particularly vulnerable. The remote exploitability without user interaction increases the urgency for patching. While no known exploits are currently active, the presence of this vulnerability in widely used web infrastructure components means it could be targeted in future attacks, especially as threat actors often scan for path traversal flaws to gain initial access or escalate privileges.
