CVE-2018-25031· NVD / CVE Program· CNA mitre

Swagger UI 4.1.2 and earlier could allow a remote attacker to conduct spoofing attacks.

Noroxi assessment

Priority: Monitor (action score 30/100)

  • A ready-made attack module is public (Nuclei); exploiting it takes no special expertise.
  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 42.3% (FIRST EPSS); higher than 98.6% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: org.webjars:swagger-ui (Maven) 4.1.3; swagger-ui (npm) 4.1.3.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to org.webjars:swagger-ui (Maven) 4.1.3; swagger-ui (npm) 4.1.3 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Swagger UI 4.1.2 and earlier could allow a remote attacker to conduct spoofing attacks. By persuading a victim to open a crafted URL, an attacker could exploit this vulnerability to display remote OpenAPI definitions. Note: This was originally claimed to be resolved in 4.1.3. However, third parties have indicated this is not resolved in 4.1.3 and even occurs in that version and possibly others.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
