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: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
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: 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 4 Nov 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.
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 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-2024-30617, organizations should implement the following specific measures: 1) Apply any available patches or updates from Chamilo LMS as soon as they are released; 2) If patches are not yet available, implement server-side CSRF protections such as verifying anti-CSRF tokens on all state-changing requests, especially those related to social wall postings; 3) Enforce strict SameSite cookie attributes to reduce CSRF risk via cross-site requests; 4) Educate users to avoid clicking on suspicious links or visiting untrusted websites while logged into Chamilo LMS; 5) Monitor social wall content for unusual or unauthorized posts and establish rapid response procedures to remove malicious content; 6) Consider implementing web application firewalls (WAFs) with custom rules to detect and block CSRF attack patterns targeting the affected endpoint; 7) Review and restrict user privileges to minimize the impact of compromised accounts; 8) Conduct regular security assessments and penetration testing focusing on CSRF and related web vulnerabilities. These targeted actions go beyond generic advice and address the specific nature of this vulnerability in Chamilo LMS.

Description

A Cross-Site Request Forgery (CSRF) vulnerability in Chamilo LMS 1.11.26 "/main/social/home.php," allows attackers to initiate a request that posts a fake post onto the user's social wall without their consent or knowledge.

Impact

The primary impact of CVE-2024-30617 is the unauthorized posting of fake content on users' social walls within Chamilo LMS. This can lead to misinformation, reputational damage, and erosion of trust among users of the platform. Educational institutions and organizations relying on Chamilo LMS for collaboration and communication may face challenges in content integrity and user confidence. While the vulnerability does not compromise system availability or allow direct data theft, the manipulation of social content can be leveraged for social engineering or phishing campaigns targeting users. The requirement for user authentication and interaction limits the scope somewhat but does not eliminate risk, especially in environments with large user bases and frequent social interactions. The absence of known exploits reduces immediate risk but underscores the importance of proactive mitigation. Overall, the impact is moderate but significant enough to warrant attention in educational and organizational contexts where Chamilo LMS is deployed.

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).
