SB20230418187 - Multiple vulnerabilities in PeopleSoft Enterprise PeopleTools

Description

This security bulletin contains information about 9 secuirty vulnerabilities.

1) Improper input validation (CVE-ID: CVE-2023-21981)

The vulnerability allows a remote privileged user to gain access to sensitive information.

The vulnerability exists due to improper input validation within the Elastic Search component in PeopleSoft Enterprise PeopleTools. A remote privileged user can exploit this vulnerability to gain access to sensitive information.

2) Improper input validation (CVE-ID: CVE-2023-21916)

The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.

The vulnerability exists due to improper input validation within the Web Server component in PeopleSoft Enterprise PeopleTools. A remote non-authenticated attacker can exploit this vulnerability to gain access to sensitive information.

3) Cross-site scripting (CVE-ID: CVE-2022-36033)

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

The vulnerability exists due to insufficient sanitization of HTML code within the jsoup cleaner, including javascript: URL expressions when the non-default SafeList.preserveRelativeLinks option is enabled. A remote attacker can inject and 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.

4) Insufficient verification of data authenticity (CVE-ID: CVE-2021-37533)

The vulnerability allows an attacker to redirect victim to a malicious host.

The vulnerability exists due to the application trusts the host from PASV response by default. A remote attacker can trick the victim into connecting to an attacker controlled FTP server and then redirect the application to another host.

5) Out-of-bounds write (CVE-ID: CVE-2022-45685)

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

The vulnerability exists due to a boundary error when processing crafted JSON data. A remote attacker can pass specially crafted input to the application, trigger an out-of-bounds write and perform a denial of service (DoS) attack.

6) Improper input validation (CVE-ID: CVE-2022-34169)

The vulnerability allows a remote non-authenticated attacker to compromise the affected system.

The vulnerability exists due to an integer truncation issue when processing malicious XSLT stylesheets. A remote non-authenticated attacker can pass specially crafted data to the application to corrupt Java class files generated by the internal XSLTC compiler and execute arbitrary Java bytecode.

7) Infinite loop (CVE-ID: CVE-2022-41881)

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

The vulnerability exists due to infinite loop within the HaProxyMessageDecoder when parsing a TLV with type of "PP2_TYPE_SSL". A remote attacker can pass a specially crafted message to consume all available system resources and cause denial of service conditions.

8) Deserialization of Untrusted Data (CVE-ID: CVE-2022-45047)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to insecure input validation when processing serialized data within the org.apache.sshd.server.keyprovider.SimpleGeneratorHostKeyProvider class. A remote attacker can pass specially crafted data to the application and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

9) Input validation error (CVE-ID: CVE-2020-14343)

The vulnerability allows a remote attacker to compromise the affected system.

The vulnerability exists due to insufficient validation of user-supplied input when processing untrusted YAML files through the full_load method or with the FullLoader loader. A remote attacker can pass specially crafted input to the application and execute arbitrary code on the system by abusing the python/object/new constructor.

Note, the vulnerability exists due to incomplete patch for vulnerability #VU25823.
