Summary

CVE-2018-25169 is a high-severity Initialization of a Resource with an Insecure Default (CWE-1188) vulnerability. Its CVSS base score is 8.7 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 26th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SC-5 (Denial-of-service Protection) and SC-6 (Resource Availability) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2018-25169 is a denial of service vulnerability in AMPPS 2.7. The flaw allows remote attackers to crash the service by sending malformed data to the default HTTP port. Attackers can establish multiple socket connections and transmit invalid payloads, exhausting server resources and causing service unavailability. It carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) and maps to CWE-1188.

Remote attackers can exploit this vulnerability over the network with low complexity and no privileges or user interaction required. By repeatedly opening socket connections to the HTTP port and sending crafted invalid data, they can overwhelm the server, resulting in a crash and complete denial of service that renders the AMPPS service unavailable.

Advisories and proof-of-concept exploits are documented in references including Exploit-DB (https://www.exploit-db.com/exploits/45850) and Vulncheck (https://www.vulncheck.com/advisories/ampps-denial-of-service-via-malformed-socket-connection). The CVE was published on 2026-03-06T13:15:58.057.

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly protects against denial-of-service events like resource exhaustion from multiple malformed socket connections and invalid payloads.

prevent

Ensures resource availability by allocating and prioritizing resources to mitigate exhaustion attacks via repeated connections.

prevent

Validates information inputs to block malformed data from causing server crashes and service unavailability.

PR.PS-01 full match
prevents

Hardened baselines and configuration management directly replace insecure defaults with secure settings.

PR.PS-06 mostly match
prevents

Secure development practices include designing products with secure defaults rather than insecure ones.

ID.RA-09 partial match
prevents

Pre-acquisition integrity checks can reject products known to ship with insecure defaults.

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.

prevents

Mandating secure baseline templates and immediate replacement of vendor defaults directly stops systems from being deployed with insecure factory settings that attackers can exploit.

prevents

Requiring documented specification, testing, and acceptance of changes ensures that new or modified components are not initialized with insecure default settings that would otherwise be left in production.

none

Requiring suppliers to document secure configuration and implemented security functions reduces the likelihood that products will be initialised with insecure default settings.
