Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2017-1556 in the wild and no public exploit code.\n\nAffected product: Ibm Api Connect. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2017-1556/ (Markdown: https://insights.sbomify.com/CVE-2017-1556/index.md)","id":"CVE-2017-1556","markdown":"https://insights.sbomify.com/CVE-2017-1556/index.md","name":"CVE-2017-1556","record":{"aliases":["GHSA-7c55-xcq9-wjvm"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"IBM API Connect","requires_auth":"low_privilege","summary":"An authenticated attacker can cause system slowdowns or hangs in IBM API Connect by exploiting a regular expression vulnerability.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ibm","cpe":[{"product":"api_connect","vendor":"ibm"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"IBM API Connect 5.0.7.0 through 5.0.7.2 is vulnerable to a regular expression attack that could allow an authenticated attacker to use a regex and cause the system to slow or hang.
