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-2020-28924 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/rclone/rclone (Go): affected all versions; fixed in 1.53.3\n- github.com/rclone/rclone (Go): affected all versions; fixed in 1.53.3\n- github.com/rclone/rclone (Go): affected all versions; fixed in 1.53.3\n- rclone (Bitnami): affected all versions; fixed in 1.53.3\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-2020-28924/ (Markdown: https://insights.sbomify.com/CVE-2020-28924/index.md)","id":"CVE-2020-28924","markdown":"https://insights.sbomify.com/CVE-2020-28924/index.md","name":"CVE-2020-28924","record":{"aliases":["BIT-rclone-2020-28924","DEBIAN-CVE-2020-28924","GHSA-rmw5-xpg9-jr29","GO-2022-0878","JLSEC-2026-278","openSUSE-SU-2020:2008-1","openSUSE-SU-2020:2035-1","openSUSE-SU-2020:2168-1","openSUSE-SU-2021:0272-1","openSUSE-SU-2024:11297-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Rclone backup tool","requires_auth":"none","summary":"Weak random number generation in Rclone produces low-entropy passwords, allowing attackers to decrypt encrypted data via dictionary attacks.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"fedora","vendor":"fedoraproject"},{"product":"rclone","vendor":"rclone"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","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-338","name":"Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG)"},{"id":"CWE-331","name":"Insufficient Entropy"}],"description":"An issue was discovered in Rclone before 1.53.3. Due to the use of a weak random number generator, the password generator has been producing weak passwords with much less entropy than advertised. The suggested passwords depend deterministically on the time the second rclone was started. This limits the entropy of the passwords enormously. These passwords are often used in the crypt backend for encryption of data. It would be possible to make a dictionary of all possible passwords with about 38 million entries per password length. This would make decryption of secret material possible with a plausible amount of effort. NOTE: all passwords generated by affected versions should be changed.","ecosystems":["Bitnami","Go","SUSE:Package Hub 15 SP1","SUSE:Package Hub 15 SP2","openSUSE:Leap 15.1","openSUSE:Leap 15.2","openSUSE:Tumbleweed"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Use of Cryptographically Weak Pseudo-Random Number Generator in Rclone","id":"CVE-2020-28924","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"fedoraproject:fedora","products":["fedoraproject:fedora"],"type":"weak_cryptography","year":"2020"},"n_packages":9,"n_references":4,"next":{"headline":"OS Command injection in Bolt","id":"CVE-2020-28925"},"packages":[{"ecosystem":"Bitnami","fixed":["1.53.3"],"introduced":["0"],"last_affected":[],"package":"rclone","purl":"pkg:bitnami/rclone","source":"BIT-rclone-2020-28924"},{"ecosystem":"Go","fixed":["1.53.3"],"introduced":["0"],"last_affected":[],"package":"github.com/rclone/rclone","purl":null,"source":"GHSA-rmw5-xpg9-jr29"},{"ecosystem":"Go","fixed":["1.53.3"],"introduced":["0"],"last_affected":[],"package":"github.com/rclone/rclone","purl":"pkg:golang/github.com/rclone/rclone","source":"GHSA-rmw5-xpg9-jr29"},{"ecosystem":"Go","fixed":["1.53.3"],"introduced":["0"],"last_affected":[],"package":"github.com/rclone/rclone","purl":"pkg:golang/github.com/rclone/rclone","source":"GO-2022-0878"},{"ecosystem":"SUSE:Package Hub 15 SP1","fixed":["1.53.3-bp151.4.6.1"],"introduced":["0"],"last_affected":[],"package":"rclone","purl":"pkg:rpm/suse/rclone\u0026distro=SUSE%20Package%20Hub%2015%20SP1","source":"openSUSE-SU-2020:2168-1"},{"ecosystem":"SUSE:Package Hub 15 SP2","fixed":["1.53.3-bp152.2.4.11"],"introduced":["0"],"last_affected":[],"package":"rclone","purl":"pkg:rpm/suse/rclone\u0026distro=SUSE%20Package%20Hub%2015%20SP2","source":"openSUSE-SU-2021:0272-1"},{"ecosystem":"openSUSE:Leap 15.1","fixed":["1.53.3-lp151.3.6.1"],"introduced":["0"],"last_affected":[],"package":"rclone","purl":"pkg:rpm/opensuse/rclone\u0026distro=openSUSE%20Leap%2015.1","source":"openSUSE-SU-2020:2035-1"},{"ecosystem":"openSUSE:Leap 15.2","fixed":["1.53.3-lp152.2.3.1"],"introduced":["0"],"last_affected":[],"package":"rclone","purl":"pkg:rpm/opensuse/rclone\u0026distro=openSUSE%20Leap%2015.2","source":"openSUSE-SU-2020:2008-1"},{"ecosystem":"openSUSE:Tumbleweed","fixed":["1.55.1-1.3"],"introduced":["0"],"last_affected":[],"package":"rclone","purl":"pkg:rpm/opensuse/rclone\u0026distro=openSUSE%20Tumbleweed","source":"openSUSE-SU-2024:11297-1"}],"prev":{"headline":"Data Amplification in Play Framework","id":"CVE-2020-28923"},"products":["n/a"],"published":"2020-11-19","related":[{"cvss_score":9.8,"headline":"PHP-CGI OS Command Injection","id":"CVE-2024-4577","kev_date_added":"2024-06-12","published":"2024-06-09"},{"cvss_score":9.8,"headline":"Grafana Authentication Bypass","id":"CVE-2021-39226","kev_date_added":"2022-08-25","published":"2021-10-05"},{"cvss_score":9.8,"headline":"VMware ESXi and Horizon DaaS OpenSLP Heap-Based Buffer Overflow","id":"CVE-2019-5544","kev_date_added":"2021-11-03","published":"2019-12-06"},{"cvss_score":9.6,"headline":"Google Chromium V8 Type Confusion","id":"CVE-2024-4947","kev_date_added":"2024-05-20","published":"2024-05-15"},{"cvss_score":9.6,"headline":"Google Chromium Visuals Use-After-Free","id":"CVE-2024-4671","kev_date_added":"2024-05-13","published":"2024-05-09"},{"cvss_score":9.6,"headline":"Google Chromium Mojo Insufficient Data Validation","id":"CVE-2022-3075","kev_date_added":"2022-09-08","published":"2022-09-26"},{"cvss_score":9.6,"headline":"Google Chromium Indexed DB API Use-After-Free","id":"CVE-2021-30633","kev_date_added":"2021-11-03","published":"2021-10-08"}],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"},{"class":"attribution","licence":"CC BY 4.0","name":"SUSE","prefix":"openSUSE"},{"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"Weak random number generation in Rclone produces low-entropy passwords, allowing attackers to decrypt encrypted data via dictionary attacks.","url":"https://insights.sbomify.com/CVE-2020-28924/"}
