Deeper analysis
CVE-2024-48955 is a broken access control vulnerability in NetAdmin version 4.030319. The affected component is the endpoint responsible for assembling functionality menus, which returns unencrypted data containing available features without performing any session authorization validation.
An attacker with low privileges can exploit the flaw over the network by copying the browser response content observed from a higher-privileged user session. This grants the attacker access to the same set of administrative functionalities without requiring further authentication or interaction, resulting in high confidentiality and integrity impacts.
The EPSS score for the vulnerability has remained flat at 0.1448 with no material increase since disclosure. Public references include a technical overview on GitHub and product information from the vendor, though no specific patch or mitigation details are provided in the available sources.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
The access control policy and procedures directly mandate and enforce proper access control mechanisms across the organization.
Device lock enforces restricted access until re-authentication, directly reducing unauthorized use of active sessions.
Supervision and review of access control activities directly detects and remediates improper access configurations or usages.
Explicitly identifying and documenting actions permitted without identification or authentication enforces proper access control boundaries by defining justified exceptions.
By automatically labeling outputs with security attributes, the control supports attribute-based enforcement and reduces exploitability of improper access control weaknesses.
Associating and retaining security attributes with data directly supports enforcement of access control decisions across storage, processing, and transmission.
Requiring prior authorization for each remote access type prevents improper access control over remote connections.
Requiring authorization of wireless access before allowing connections enforces proper access control for this access method.
