CVE-2020-12529
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 · uneditedAn issue was discovered in MB connect line mymbCONNECT24 and mbCONNECT24 software in all versions through V2.6.2 There is a SSRF in the LDAP access check, allowing an attacker to scan for open ports.
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 confidenceAn SSRF vulnerability exists in the LDAP access check functionality of mbCONNECT24 and mymbCONNECT24 (all versions through V2.6.2). Attackers can manipulate the LDAP authentication flow to make the server perform arbitrary requests, enabling internal network port scanning.

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 installed product versionLocate the version information for mbCONNECT24 or mymbCONNECT24 installed in your environment. This is typically found in the application interface under 'About' or 'System Info', or in installation/upgrade logs.Affected if The installed version is V2.6.2 or lower.
-
Confirm LDAP authentication is in useCheck the application configuration or authentication settings to determine if LDAP is enabled as an authentication provider. This vulnerability only affects systems using LDAP integration.Affected if LDAP authentication is configured and active.
-
Review authentication logs for LDAP anomaliesExamine authentication and access logs for unusual LDAP queries or patterns that may indicate manipulation of the LDAP authentication flow. Look for unexpected connection attempts or requests originating from the application server.Affected if Log entries show LDAP requests to unexpected internal IP addresses or unusual query patterns.
-
Monitor network connections from the application serverInspect outbound network connections originating from the mbCONNECT24/mymbCONNECT24 server, particularly to internal network addresses on non-standard ports.Affected if The server is making outbound connections to internal IP addresses or ports that were not intentionally configured.
Your environment is affected if you are running mbCONNECT24 or mymbCONNECT24 at version 2.6.2 or lower with LDAP authentication enabled.

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 dataUpgrade to a patched version beyond V2.6.2. If no patch is available, implement network segmentation and restrict outbound access from the server to limit the impact of SSRF exploitation.
