CVE-2024-5675
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedUntrusted data deserialization vulnerability has been found in Mentor - Employee Portal, affecting version 3.83.35. This vulnerability could allow an attacker to execute arbitrary code, by injecting a malicious payload into the “ViewState” field.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceUntrusted deserialization vulnerability in Mentor Employee Portal v3.83.35 allows remote attackers to execute arbitrary code by injecting malicious payloads into the ViewState field, which is deserialized without proper validation.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the installed Mentor Employee Portal versionLocate the application binary or check the software inventory/system information for Summar Mentor version 3.83.35Affected if The installed version is exactly 3.83.35
-
Confirm ViewState is in useInspect the application configuration files (web.config or similar) for ViewState settings or examine HTTP responses for __VIEWSTATE hidden form fieldsAffected if ViewState is enabled and processed by the application
-
Check ViewState MAC validation statusExamine the web.config file for the enableViewStateMac attribute; if present and set to false, or if the attribute is missing and defaults to false, MAC validation is disabledAffected if enableViewStateMac is set to false or is absent with default disabled behavior
-
Verify ViewState validation keys are configuredInspect the machineKey configuration in web.config; check if validationKey is set to a strong, unique value or if it is auto-generated/emptyAffected if Validation keys are missing, auto-generated, or use weak/default values
-
Check for exposed endpoints accepting ViewStateReview HTTP traffic or application logs for POST requests to sensitive pages that accept ViewState data without additional authentication layersAffected if Unauthenticated or weakly authenticated endpoints accept and deserialize ViewState data
You are affected if running Summar Mentor version 3.83.35 with ViewState enabled and either MAC validation disabled or weak/missing validation keys.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement ViewState validation with machine-level validation keys, enable viewstate MAC validation, or upgrade to a patched version if available; also restrict access to vulnerable endpoints at the network level.
