Description
This security bulletin contains information about 11 secuirty vulnerabilities.
1) Incorrect default permissions (CVE-ID: CVE-2020-8908)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to incorrect default permissions for files located in the temporary directory set by the Guava com.google.common.io.Files.createTempDir(). A local user with access to the system can view contents of files and directories or modify them.
2) Improper Certificate Validation (CVE-ID: CVE-2021-44533)
The vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to improper validation of certificate subject and issuer fields. A remote attacker can create a certificate with specially crafted multi-value Relative Distinguished Names and perform spoofing attack.
3) Cross-site scripting (CVE-ID: CVE-2021-41165)
The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of user-supplied data when processing HTML comments. 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) Cryptographic issues (CVE-ID: CVE-2021-4160)
The vulnerability allows a remote attacker to decrypt TLS traffic.
The vulnerability exists due to BN_mod_exp may produce incorrect results on MIPS. A remote attacker can decrypt TLS traffic. According to vendor, multiple EC algorithms are affected, including some of the TLS 1.3 default curves.
Successful exploitation of the vulnerability requires certain pre-requisites for attack, such as obtaining and reusing private keys.
5) Improper input validation (CVE-ID: CVE-2022-21470)
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
The vulnerability exists due to improper input validation within the Process Scheduler component in PeopleSoft Enterprise PeopleTools. A remote non-authenticated attacker can exploit this vulnerability to read and manipulate data.
6) Improper input validation (CVE-ID: CVE-2022-21458)
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
The vulnerability exists due to improper input validation within the Navigation Pages, Portal, Query component in PeopleSoft Enterprise PeopleTools. A remote non-authenticated attacker can exploit this vulnerability to read and manipulate data.
7) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2021-43797)
The vulnerability allows a remote attacker to preform HTTP request smuggling attacks.
The vulnerability exists due to improper validation of HTTP requests when processing control chars present at the beginning / end of the header name. A remote attacker can send a specially crafted HTTP request to the server and smuggle arbitrary HTTP headers.
Successful exploitation of vulnerability may allow an attacker to poison HTTP cache and perform phishing attacks.
8) Code Injection (CVE-ID: CVE-2021-44832)
The vulnerability allows a remote user to execute arbitrary code on the target system.
The vulnerability exists due to improper input validation. A remote user with permission to modify the logging configuration file can construct a malicious configuration using a JDBC Appender with a data source referencing a JNDI URI which can execute remote code.
9) Information disclosure (CVE-ID: CVE-2021-40690)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to an issue where the "secureValidation" property is not passed correctly when creating a KeyInfo from a KeyInfoReference element. A remote attacker can abuse an XPath Transform to extract any local .xml files in a RetrievalMethod element.
10) Infinite loop (CVE-ID: CVE-2021-37714)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop when processing untrusted HTML and XML code. A remote attacker can consume all available system resources and cause denial of service conditions.
11) Use-after-free (CVE-ID: CVE-2021-3518)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in libxml2. A remote attacker can use a specially crafted file and execute arbitrary code on the target system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
