Cisco Wireless LAN Controller Software contains a vulnerability that could allow an authenticated, remote attacker to conduct cross-site scripting attacks. Updates are not available.
Cisco Wireless LAN Controller Software contains a vulnerability that could allow an authenticated, remote attacker to conduct cross-site scripting attacks.
The vulnerability is due to improper validation of user-supplied input to the affected software. An authenticated, remote attacker could exploit the vulnerability by sending malicious requests to the targeted system. When processed, the requests could cause the vulnerable software to store malicious script that when viewed by another user could execute arbitrary script or HTML code in the user's browser.
Cisco confirmed the vulnerability in a security bug report; however, software updates are unavailable.
Cisco Wireless LAN Controller Software versions 7.2 and prior are vulnerable.
Only users who can authenticate to the affected software could exploit the vulnerability. Affected systems typically have restricted access, limiting the potential for exploitation.
A related vulnerability in the affected software could allow an unauthenticated, remote attacker to exploit the vulnerability. However, the exploit relies upon user interaction, and the targeted user must have authenticated access to the affected system.
Vendor announcements are unavailable.
An authenticated, remote attacker could exploit the vulnerability to execute arbitrary script code in a user's browser, possibly allowing the attacker to gain access to sensitive browser-based information.
The vulnerability is due to improper validation of input to the web_auth_custom.html script of the Cisco Wireless LAN Controller Software web-based management interface.
An authenticated, remote attacker could exploit this vulnerability by sending malicious input to the affected script via HTTP POST requests. When processed, the affected software may store input within the malicious requests within the vulnerable script. If a user later views the script, the malicious input may be included in the user's browser, allowing the attacker to conduct cross-site scripting attacks.
Administrators are advised to contact the vendor regarding future updates and releases.
Administrators are advised to allow only trusted users to have network access.
Administrators are advised to monitor affected systems.
