A vulnerability in the Profile Editor of the Cisco AnyConnect Secure Mobility Client could allow an unauthenticated, local attacker to have read and write access to information stored in the affected system. The vulnerability is due to improper handling of the XML External Entity (XXE) entries when parsing an XML file. An attacker could exploit this vulnerability by injecting a crafted XML file with malicious entries, which could allow the attacker to read and write files. Cisco Bug IDs: CSCvg19341.

A stack-based Buffer Overflow Vulnerability exists in the web server in Pulse Secure Pulse Connect Secure (PCS) before 8.3R4 and Pulse Policy Secure (PPS) before 5.4R4, leading to memory corruption and possibly remote code execution.

A cross site scripting issue has been found in custompage.cgi in Pulse Secure Pulse Connect Secure (PCS) before 8.0R17.0, 8.1.x before 8.1R13, 8.2.x before 8.2R9, and 8.3.x before 8.3R3 and Pulse Policy Secure (PPS) before 5.2R10, 5.3.x before 5.3R9, and 5.4.x before 5.4R3 due to one of the URL parameters not being sanitized. Exploitation does require the user to be logged in as administrator; the issue is not applicable to the end user portal.

A vulnerability in the Network Access Manager (NAM) of Cisco AnyConnect Secure Mobility Client could allow an authenticated, local attacker to enable multiple network adapters, aka a Dual-Homed Interface vulnerability. The vulnerability is due to insufficient NAM policy enforcement. An attacker could exploit this vulnerability by manipulating network interfaces of the device to allow multiple active network interfaces. A successful exploit could allow the attacker to send traffic over a non-authorized network interface. Cisco Bug IDs: CSCvf66539.

diag.cgi in Pulse Connect Secure 8.2R1 through 8.2R5, 8.1R1 through 8.1R10 and Pulse Policy Secure 5.3R1 through 5.3R5, 5.2R1 through 5.2R8, and 5.1R1 through 5.1R10 allow remote attackers to hijack the authentication of administrators for requests to start tcpdump, related to the lack of anti-CSRF tokens.

The WebLaunch functionality of Cisco AnyConnect Secure Mobility Client Software contains a vulnerability that could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the affected software. The vulnerability is due to insufficient input validation of some parameters that are passed to the WebLaunch function of the affected software. An attacker could exploit this vulnerability by convincing a user to access a malicious link or by intercepting a user request and injecting malicious code into the request. Cisco Bug IDs: CSCvf12055. Known Affected Releases: 98.89(40).

Pulse Connect Secure 8.3R1 has CSRF in diag.cgi. In the panel, the diag.cgi file is responsible for running commands such as ping, ping6, traceroute, traceroute6, nslookup, arp, and Portprobe. These functions do not have any protections against CSRF. That can allow an attacker to run these commands against any IP if they can get an admin to visit their malicious CSRF page.

Pulse Connect Secure 8.3R1 has CSRF in logout.cgi. The logout function of the admin panel is not protected by any CSRF tokens, thus allowing an attacker to logout a user by making them visit a malicious web page.

Pulse Connect Secure 8.3R1 has Reflected XSS in adminservercacertdetails.cgi. In the admin panel, the certid parameter of adminservercacertdetails.cgi is reflected in the application's response and is not properly sanitized, allowing an attacker to inject tags. An attacker could come up with clever payloads to make the system run commands such as ping, ping6, traceroute, nslookup, arp, etc.

Pulse Connect Secure 8.3R1 has Reflected XSS in launchHelp.cgi. The helpLaunchPage parameter is reflected in an IFRAME element, if the value contains two quotes. It properly sanitizes quotes and tags, so one cannot simply close the src with a quote and inject after that. However, an attacker can use javascript: or data: to abuse this.
