Due to the rcp implementation being derived from 1983 rcp, the server chooses which files/directories are sent to the client. However, the rcp client only performs cursory validation of the object name returned (only directory traversal attacks are prevented). A malicious rcp server (or Man-in-The-Middle attacker) can overwrite arbitrary files in the rcp client target directory. If recursive operation (-r) is performed, the server can manipulate subdirectories as well (for example, to overwrite the .ssh/authorized_keys file). This issue is similar to CVE-2019-6111 and CVE-2019-7283. NOTE: MIT krb5-appl is not supported upstream but is shipped by a few Linux distributions. The affected code was removed from the supported MIT Kerberos 5 (aka krb5) product many years ago, at version 1.8.","state":"PUBLIC","assigner":"cve@mitre.org","published_at":"2021-02-02 18:15:00","updated_at":"2021-07-21 11:39:00"},"problem_types":["CWE-863"],"metrics":[],"references":[{"url":"https://bugzilla.suse.com/show_bug.cgi?id=1131109","name":"https://bugzilla.suse.com/show_bug.cgi?id=1131109","refsource":"MISC","tags":["Exploit","Issue Tracking","Third Party Advisory"],"title":"Bug 1131109 – VUL-0: CVE-2019-25017,CVE-2019-25018: krb5-appl: affects krb5-appl kerberized rcp (related to CVE-2019-6111)","mime":"text/html","httpstatus":"200","archivestatus":"200"},{"url":"https://www.cve.org/CVERecord?id=CVE-2019-25017","name":"CVE Program record","refsource":"CVE.ORG","tags":["canonical"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2019-25017","name":"NVD vulnerability detail","refsource":"NVD","tags":["canonical","analysis"]}],"affected":[],"timeline":[],"solutions":[],"workarounds":[],"exploits":[],"credits":[],"nvd_cpes":[{"cve_year":"2019","cve_id":"25017","vulnerable":"1","versionEndIncluding":"1.0.3","cpe1":"cpe","cpe2":"2.3","cpe3":"a","cpe4":"mit","cpe5":"krb5-appl","cpe6":"*","cpe7":"*","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"*","cpe12":"*","cpe13":"*"}],"vendor_comments":[],"enrichments":{"kev":null,"epss":null,"legacy_qids":[]},"source_records":{"cve_program":{"CVE_data_meta":{"ASSIGNER":"cve@mitre.org","ID":"CVE-2019-25017","STATE":"PUBLIC"},"affects":{"vendor":{"vendor_data":[{"product":{"product_data":[{"product_name":"n/a","version":{"version_data":[{"version_value":"n/a"}]}}]},"vendor_name":"n/a"}]}},"data_format":"MITRE","data_type":"CVE","data_version":"4.0","description":{"description_data":[{"lang":"eng","value":"An issue was discovered in rcp in MIT krb5-appl through 1.0.3.
