An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2025-9071 in the wild and no public exploit code.\n\nAffected product: Oberon PSA Crypto. 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-2025-9071/ (Markdown: https://insights.sbomify.com/CVE-2025-9071/index.md)","id":"CVE-2025-9071","markdown":"https://insights.sbomify.com/CVE-2025-9071/index.md","name":"CVE-2025-9071","record":{"aliases":["GHSA-5h27-5x9j-ffpx"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Oberon PSA Crypto library","requires_auth":"none","summary":"Insecure RSA-OAEP implementation using an all-zero seed allows attackers to decrypt guessable messages and identify repeated ciphertexts in Oberon PSA Crypto.","user_interaction":"required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"NCSC.ch","cpe":[],"cvss":{"score":2.3,"severity":"low","source":"cna","vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:P/VC:L/VI:N/VA:N/SC:L/SI:N/SA:N/S:N/RE:L","version":"4.0"},"cwes":[{"id":"CWE-780","name":"Use of RSA Algorithm without OAEP"}],"description":"Erroneously using an all-zero seed for RSA-OEAP padding instead of the generated random bytes, in Oberon microsystems AG’s Oberon PSA Crypto library in all versions up to 1.5.1, results in deterministic RSA and thus in a loss of confidentiality for guessable messages, recognition of repeated messages, and loss of security proofs.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Insecure RSA-OAEP implementation with all-zero seed for padding in Oberon PSA Crypto","id":"CVE-2025-9071","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"weak_cryptography","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"One-Click Mattermost Account Takeover via Poisoned RelayState SAML Parameter","id":"CVE-2025-9072"},"packages":[],"prev":{"headline":"Rockwell Automation FactoryTalk® Linx Privilege Escalation Vulnerabilities","id":"CVE-2025-9068"},"products":["Oberon PSA Crypto"],"published":"2025-08-29","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-08-29","vendors":["Oberon microsystems AG"]},"summary":"Insecure RSA-OAEP implementation using an all-zero seed allows attackers to decrypt guessable messages and identify repeated ciphertexts in Oberon PSA Crypto.","url":"https://insights.sbomify.com/CVE-2025-9071/"}
