CVE-2024-11680
Access Control in Projectsend ≤ r1720
Raw vector
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2024-11680 is a critical-severity Missing Authentication for Critical Function (CWE-306) vulnerability in Projectsend Projectsend. Its CVSS base score is 9.8 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique System Service Discovery (T1007); ranked in the top 0.2% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified map to AC-14 (Permitted Actions Without Identification or Authentication) and IA-2 (Identification and Authentication (Organizational Users)) — see the control section below for these in your framework.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
ProjectSend versions prior to r1720 contain an improper authentication vulnerability tracked as CVE-2024-11680. The flaw resides in the options.php endpoint and stems from missing authentication checks, allowing remote attackers to alter application configuration settings without any credentials. The issue carries a CVSS 3.1 score of 9.8 and is classified under CWE-306.
Unauthenticated attackers can exploit the weakness by submitting specially crafted HTTP requests to options.php. Successful exploitation grants the ability to create new administrative accounts, upload webshells, and inject arbitrary JavaScript into the application, resulting in full compromise of the affected instance.
Public references, including the official ProjectSend commit and the Synacktiv advisory, indicate that the vulnerability is resolved in release r1720; administrators should upgrade immediately. Detection templates for Nuclei and an exploit module in Metasploit Framework are also available, while the EPSS score remains elevated above 0.93.

Mitigating Controls (NIST 800-53 r5) AI
Directly mandates unique identification and authentication of users before access to functions requiring identity.
Extends the same authentication requirement to non-organizational users accessing critical functionality.
Requires authentication of services before they can invoke or expose critical functions.
Explicitly identifies and limits actions permitted without authentication, preventing critical functions from being exposed.
Access enforcement requires prior authentication before any authorization decision for critical functions.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Managing identities and credentials is a prerequisite for authentication but does not itself enforce it on critical functions.
Directly requires authentication of users/services/hardware, which eliminates missing authentication for critical functions.
Defining and enforcing authorizations assumes prior authentication and therefore only partially mitigates the absence of authentication.
Protecting networks from unauthorized access can be undermined by missing authentication but does not address the root authentication gap.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Mandating authentication requirements for critical functions at the requirements-gathering stage ensures that essential operations are not left unprotected by missing login or verification mechanisms.
