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-2023-31277 in the wild and no public exploit code.\n\nAffected product: PiiGAB  M-Bus SoftwarePack. 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-2023-31277/ (Markdown: https://insights.sbomify.com/CVE-2023-31277/index.md)","id":"CVE-2023-31277","markdown":"https://insights.sbomify.com/CVE-2023-31277/index.md","name":"CVE-2023-31277","record":{"aliases":["GHSA-pm8c-wh6q-xfwq"],"analysis":{"component_type":"ics_ot","fix_type":"no_fix_stated","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"M-Bus SoftwarePack","requires_auth":"none","summary":"PiiGAB M-Bus transmits credentials in plaintext, allowing attackers to intercept sensitive authentication data.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"m-bus_900s_firmware","vendor":"piigab"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-523","name":"Unprotected Transport of Credentials"}],"description":"PiiGAB M-Bus transmits credentials in plaintext format.","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":"PiiGAB M-Bus Unprotected Transport of Credentials","id":"CVE-2023-31277","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Horner Automation Cscape Out-of-bounds Read","id":"CVE-2023-31278"},"packages":[],"prev":{"headline":"Memory corruption in Intel(R) Server Board S2600WF, Intel(R) Server Board S2600ST, Intel(R) Server Board S2600BP, Intel(R) Server Board M50CYP and Intel(R) Server Board D50TNP","id":"CVE-2023-31276"},"products":["M-Bus SoftwarePack"],"published":"2023-07-06","related":[{"cvss_score":9.8,"headline":"PiiGAB M-Bus Use of Hard-coded Credentials","id":"CVE-2023-35987","kev_date_added":null,"published":"2023-07-06"},{"cvss_score":8.8,"headline":"PiiGAB M-Bus Cross-Site Request Forgery","id":"CVE-2023-35120","kev_date_added":null,"published":"2023-07-06"},{"cvss_score":8.8,"headline":"PiiGAB M-Bus Code Injection","id":"CVE-2023-36859","kev_date_added":null,"published":"2023-07-06"},{"cvss_score":8,"headline":"PiiGAB M-Bus Cross-site Scripting","id":"CVE-2023-32652","kev_date_added":null,"published":"2023-07-06"},{"cvss_score":7.5,"headline":"PiiGAB M-Bus Use of Password Hash With Insufficient Computational Effort","id":"CVE-2023-34433","kev_date_added":null,"published":"2023-07-06"},{"cvss_score":7.5,"headline":"PiiGAB M-Bus Weak Password Requirements","id":"CVE-2023-34995","kev_date_added":null,"published":"2023-07-06"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-11-14","vendors":["PiiGAB "]},"summary":"PiiGAB M-Bus transmits credentials in plaintext, allowing attackers to intercept sensitive authentication data.","url":"https://insights.sbomify.com/CVE-2023-31277/"}
