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: High: A successful attack depends on conditions beyond the attacker's control. That is, a successful attack cannot be accomplished at will, but requires the attacker to invest in some measurable amount of effort in preparation or execution against the vulnerable component before a successful attack can be expected. For example, a successful attack may require an attacker to: gather knowledge about the environment in which the vulnerable target/component exists; prepare the target environment to improve exploit reliability; or inject themselves into the logical network path between the target and the resource requested by the victim in order to read and/or modify network communications (e.g., a man in the middle attack).
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: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
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.

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 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-2024-41262, organizations should immediately assess their use of mmudb v1.9.3 and identify deployments of the ShowMetricsRaw and ShowMetricsAsText functions. Since no official patches are currently available, the following steps are recommended: 1) Implement network-level protections such as VPNs or encrypted tunnels (e.g., IPsec, SSH tunnels) to secure communications between clients and mmudb servers; 2) Restrict network access to mmudb services to trusted hosts and networks using firewalls and access control lists; 3) If possible, modify or configure mmudb to use HTTPS or another encrypted protocol for metrics transmission; 4) Monitor network traffic for signs of interception or manipulation, including unexpected changes in metrics data; 5) Engage with the mmudb vendor or community to track patch releases or updates addressing this vulnerability; 6) Educate network and security teams about the risks of unencrypted protocols in monitoring tools; 7) Consider deploying intrusion detection/prevention systems (IDS/IPS) to detect MitM attack patterns on relevant network segments. These measures collectively reduce the risk of data interception and manipulation until a formal patch is available.

Description

mmudb v1.9.3 was discovered to use the HTTP protocol in the ShowMetricsRaw and ShowMetricsAsText functions, possibly allowing attackers to intercept communications via a man-in-the-middle attack.

Impact

The primary impact of CVE-2024-41262 is the exposure of sensitive metrics data transmitted by mmudb over unencrypted HTTP channels. Attackers capable of intercepting network traffic can obtain confidential information, potentially revealing system performance, usage patterns, or other operational details. This breach of confidentiality can aid further attacks or intelligence gathering. Additionally, the integrity of the data can be compromised, allowing attackers to alter metrics, which may mislead monitoring systems or trigger incorrect operational responses. Although availability is not affected, the trustworthiness of monitoring data is undermined, which can have cascading effects on incident detection and response. Organizations relying on mmudb for critical infrastructure monitoring or decision-making processes face increased risk of data leakage and manipulation. The lack of authentication requirements and user interaction lowers the barrier for exploitation, especially in environments where network access is not tightly controlled. This vulnerability can affect organizations globally, particularly those in sectors with high reliance on real-time metrics and monitoring data.

CWE-319Cleartext Transmission of Sensitive Information (opens in a new tab)
Base weaknessLikelihood of exploit: HighOWASP Top 10 A04:2025: Cryptographic Failures (opens in a new tab)
The product transmits sensitive or security-critical data in cleartext in a communication channel that can be sniffed by unauthorized actors.
Architecture and Design
Before transmitting, encrypt the data using reliable, confidentiality-protecting cryptographic protocols.
Implementation
When using web applications with SSL, use SSL for the entire session from login to logout, not just for the initial login page.
Implementation
When designing hardware platforms, ensure that approved encryption algorithms (such as those recommended by NIST) protect paths from security critical data to trusted user applications.
