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: High: The attacker is authorized with (i.e., requires) privileges that provide significant (e.g., administrative) control over the vulnerable component that could affect component-wide settings and files.
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: 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 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 27 Jun 2024
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.

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

To mitigate CVE-2024-39156, organizations should implement robust CSRF protections within the idccms administrative interface. This includes adding anti-CSRF tokens to all state-changing requests, especially those in /admin/keyWord_deal.php?mudi=add, to ensure that requests originate from legitimate sources. Additionally, enforcing same-site cookie attributes and validating the HTTP Referer header can provide supplementary defenses. Restrict administrative access to trusted IP addresses or VPNs to reduce exposure. Regularly audit and monitor administrative actions for unusual activity that could indicate exploitation attempts. Educate administrators about phishing and social engineering risks to prevent credential compromise. Finally, maintain up-to-date backups and incident response plans to recover quickly if exploitation occurs.

Description

idccms v1.35 was discovered to contain a Cross-Site Request Forgery (CSRF) via the component /admin/keyWord_deal.php?mudi=add.

Impact

The primary impact of CVE-2024-39156 is the unauthorized modification of administrative data within idccms, which could compromise the integrity and confidentiality of the system's keyword management functions. Although the vulnerability does not directly affect availability, unauthorized changes could lead to misconfigurations or data inconsistencies that degrade system reliability or user trust. Since exploitation requires high privileges (an authenticated administrator), the risk is somewhat mitigated by access controls; however, if an attacker gains administrative credentials or uses social engineering to trick an admin, they could leverage this vulnerability to perform unauthorized actions. This could facilitate further attacks, such as privilege escalation or data leakage, especially in environments where idccms is used to manage critical content or services. Organizations relying on idccms 1.35 should consider the potential for indirect impacts on their operational security and data integrity. The absence of known exploits reduces immediate risk, but the vulnerability should be addressed promptly to prevent future exploitation.

Compound weaknessLikelihood of exploit: MediumCWE Top 25 (2025): #3OWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor.
Architecture and Design · Libraries or Frameworks
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
Implementation
Ensure that the application is free of cross-site scripting issues (CWE-79), because most CSRF defenses can be bypassed using attacker-controlled script.
Architecture and Design
Generate a unique nonce for each form, place the nonce into the form, and verify the nonce upon receipt of the form. Be sure that the nonce is not predictable (CWE-330).
