[原文]Multiple cross-site scripting (XSS) vulnerabilities in cPanel 9.1.0-R85 allow remote attackers to inject arbitrary web script or HTML via the (1) email parameter to testfile.html, (2) file parameter to erredit.html, (3) dns parameter to dnslook.html, (4) account parameter to ignorelist.html, (5) account parameter to showlog.html, (6) db parameter to repairdb.html, (7) login parameter to doaddftp.html (8) account parameter to editmsg.htm, or (9) ip parameter to del.html. NOTE: the dnslook.html vector was later reported to exist in cPanel 10.
cPanel contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate the "email" variable upon submission to the "testfile.html" script. This could allow a user to create a specially crafted URL that would execute arbitrary code in a user's browser within the trust relationship between the browser and the server, leading to a loss of integrity.
Currently, there are no known upgrades, patches, or workarounds available to correct this issue.
Aria-Security Team is credited with the discovery of this vulnerability.
cPanel cPanel 10
Cpanel is prone to a cross-site scripting vulnerability because the application fails to properly sanitize user-supplied input.
An attacker may leverage this issue to have arbitrary script code execute in the browser of an unsuspecting user in the context of the affected site. This may help the attacker steal cookie-based authentication credentials and launch other attacks.
This issue affects version 10; other versions may also be vulnerable.
An attacker can exploit this issue by enticing an unsuspected vicitim to follow a malicious URI.
