An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2018-12885 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2018-12885/ (Markdown: https://insights.sbomify.com/CVE-2018-12885/index.md)","id":"CVE-2018-12885","markdown":"https://insights.sbomify.com/CVE-2018-12885/index.md","name":"CVE-2018-12885","record":{"aliases":["GHSA-h4gq-q399-xm7r"],"analysis":{"component_type":"other","fix_type":"no_fix_stated","impacts":["privilege_escalation","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Ethereum smart contract","requires_auth":"none","summary":"Attackers can predict random values in the MyCryptoChamp smart contract to obtain powerful items and rewards, undermining game integrity.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"mycryptochamp","vendor":"mycryptochamp"}],"cvss":{"score":5.9,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.0"},"cwes":[{"id":"CWE-338","name":"Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG)"}],"description":"The randMod() function of the smart contract implementation for MyCryptoChamp, an Ethereum game, generates a random value with publicly readable variables such as the current block information and a private variable, (which can be read with a getStorageAt call).
