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 · unedited
Multiple buffer overflows in DeleGate 7.7.0 through 7.8.1 allow remote attackers to execute arbitrary code, as demonstrated using a long USER command to the POP proxy.

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 · high confidence

Multiple buffer overflow vulnerabilities exist in DeleGate versions 7.7.0 through 7.8.1 in the POP proxy component. Attackers can send a specially crafted long USER command to overflow a buffer and execute arbitrary code remotely.

MitigationUpgrade DeleGate to a version beyond 7.8.1. If immediate upgrading is not possible, disable or restrict access to the POP proxy service to limit attack surface.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify if DeleGate is installed
    Locate the DeleGate executable or service on the system using commands like 'which delegate', 'where delegate', or by checking running processes
    Affected if DeleGate software is present on the system
  2. Check installed DeleGate version
    Run the DeleGate binary with version information flags (such as -v or -version) or inspect the binary file properties
    Affected if Version is 7.7.0, 7.7.1, 7.8.0, or 7.8.1
  3. Verify POP proxy is enabled
    Examine DeleGate configuration files (commonly named deleGate.conf or similar) for POP proxy module configuration
    Affected if POP proxy component is enabled in DeleGate configuration
  4. Assess POP proxy network exposure
    Check if the POP proxy service port (typically port 110 or configured port) is listening on network interfaces accessible from untrusted sources
    Affected if POP proxy is exposed to network access

System is vulnerable if DeleGate versions 7.7.0 through 7.8.1 is running with POP proxy enabled and accessible on the network

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.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade DeleGate to a version beyond 7.8.1. If immediate upgrading is not possible, disable or restrict access to the POP proxy service to limit attack surface.
