Multiple vulnerabilities in Oracle WebLogic Server

1) Cross-site scripting

EUVDB-ID: #VU65834

Risk: Low

CVSSv4.0: 0.5 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N/E:U/U:Clear]

CVE-ID: CVE-2022-31160

CWE-ID: CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to insufficient sanitization of user-supplied data when initializing a checkboxradio widget on an input enclosed within a label makes that parent label contents considered as the input label. If .checkboxradio( "refresh" ) is called on such a widget and the initial HTML contains encoded HTML entities, they will erroneously get decoded and executed. A remote attacker can execute arbitrary HTML and script code in user's browser in context of vulnerable website.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.

CVE-ID: CVE-2021-22569

CWE-ID: CWE-399 - Resource Management Errors

Exploit availability: Yes

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to improper management of internal resources within the application. protobuf-java allowes the interleaving of com.google.protobuf.UnknownFieldSet fields in such a way that would be processed out of order. A small malicious payload can occupy the parser for several minutes by creating large numbers of short-lived objects that cause frequent, repeated pauses. A remote attacker can trick the victim into passing specially crafted data to the application and perform a denial of service attack.
