https://notcve.org/view.php?id=CVE-2019-25017
An issue was discovered in rcp in MIT krb5-appl through 1.0.3. 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). • https://bugzilla.suse.com/show_bug.cgi?id=1131109 • CWE-863: Incorrect Authorization •

In the rcp client in MIT krb5-appl through 1.0.3, malicious servers could bypass intended access restrictions via the filename of . or an empty filename, similar to CVE-2018-20685 and CVE-2019-7282. The impact is modifying the permissions of the target directory on the client side. 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. En el cliente rcp en MIT krb5-appl versiones hasta 1.0.3, los servidores maliciosos podrían omitir unas restricciones de acceso previstas por medio del nombre de archivo of o un nombre de archivo vacío, similar al CVE-2018-20685 y CVE-2019-7282. • https://bugzilla.suse.com/show_bug.cgi?id=1131109 •

Buffer overflow in libtelnet/encrypt.c in telnetd in FreeBSD 7.3 through 9.0, MIT Kerberos Version 5 Applications (aka krb5-appl) 1.0.2 and earlier, Heimdal 1.5.1 and earlier, GNU inetutils, and possibly other products allows remote attackers to execute arbitrary code via a long encryption key, as exploited in the wild in December 2011. Desbordamiento de búfer basado en pila en libtelnet/encrypt.c en telnetd en FreeBSD v7.3 hasta v9.0, MIT Kerberos Version v5 Applications (también conocido como krb5-appl) v1.0.2 y anteriores, y Heimdal v1.5.1 y anteriores, permite a atacantes remotos ejecutar código de su elección a través de una clave de cifrado larga, como fue explotado en Diciembre 2011.

CVSS: 6.5EPSS: 0%CPEs: 16EXPL: 0CVE-2011-1526 – krb5-appl: ftpd incorrect group privilege dropping (MITKRB5-SA-2011-005)
https://notcve.org/view.php?id=CVE-2011-1526
ftpd.c in the GSS-API FTP daemon in MIT Kerberos Version 5 Applications (aka krb5-appl) 1.0.1 and earlier does not check the krb5_setegid return value, which allows remote authenticated users to bypass intended group access restrictions, and create, overwrite, delete, or read files, via standard FTP commands, related to missing autoconf tests in a configure script. ftpd.c en el demonio GSS-API FTP en MIT Kerberos Version 5 Applications (también conocido como krb5-appl) v1.0.1 y anteriores no comprueban el valor de retorno krb5_setegid, lo que permite que usuarios autenticados de forma remota evitar las restricciones de acceso de grupo, y crear, sobreescribir, borrar, o leer ficheros, a través de comandos FTP estándar, relacionado con test autoconfigurados olvidados en un script configurado. It was found that ftpd, a Kerberos-aware FTP server, did not properly drop privileges. On Red Hat Enterprise Linux 5, the ftpd daemon did not check for the potential failure of the krb5_setegid() function call. On systems where the set real, set effective, or set saved group ID system calls might fail, a remote FTP user could use this flaw to gain unauthorized read or write access to files that were owned by the root group. • http://lists.fedoraproject.org/pipermail/package-announce/2011-July/062681.html http://lists.fedoraproject.org/pipermail/package-announce/2011-July/062699.html http://lists.opensuse.org/opensuse-security-announce/2011-10/msg00009.html http://lists.opensuse.org/opensuse-security-announce/2012-01/msg00002.html http://lists.opensuse.org/opensuse-security-announce/2012-01/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2012-01/msg00005.html http://lists.opensuse.org/opensuse-security-announce/201 • CWE-269: Improper Privilege Management •
