Description
This security bulletin contains information about 9 secuirty vulnerabilities.
1) Open redirect (CVE-ID: N/A)
The vulnerability allows a remote attacker to redirect victims to arbitrary URL.
The vulnerability exists due to improper sanitization of user-supplied data in the OAuth sample config. A remote attacker can create a link that leads to a trusted website, however, when clicked, redirects the victim to arbitrary domain.
Successful exploitation of this vulnerability may allow a remote attacker to perform a phishing attack and steal potentially sensitive information.
2) Improper access control (CVE-ID: N/A)
The vulnerability allows a remote user to gain access to sensitive information.
The vulnerability exists due to improper access restrictions when self-service is enabled. A remote administrator can list front-end APIs via GET /proxies API of any organization.
3) Out-of-bounds write (CVE-ID: CVE-2022-40152)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error when processing untrusted input within the Woodstox XML parser. A remote attacker can pass a specially crafted input to the application, trigger an out-of-bounds write and crash the application.
4) Improper input validation (CVE-ID: CVE-2022-40153)
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper input validation within the Centralized Third Party Jars (XStream) component in Oracle WebLogic Server. A remote non-authenticated attacker can exploit this vulnerability to perform a denial of service (DoS) attack.
5) Code Injection (CVE-ID: CVE-2022-42889)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to an insecure variable interpolation when processing untrusted input. A remote attacker can send a specially crafted input and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
Note, the vulnerability was dubbed Text4shell.
6) Buffer overflow (CVE-ID: CVE-2022-3786)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The
vulnerability exists due to a boundary error when processing the email
address field length inside a X.509 certificate. A remote attacker can supply a
specially crafted certificate to the application, trigger a buffer overflow and crash the application.
7) Buffer overflow (CVE-ID: CVE-2022-3602)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing the email address field inside X.509 certificate. A remote attacker can supply a specially crafted certificate to the application, trigger a 4-byte buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system but requires that either a CA signs the malicious certificate or for the application to continue certificate verification despite failure to construct a path to a trusted issuer.
8) Use-after-free (CVE-ID: CVE-2022-40674)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in the doContent() function in xmlparse.c. A remote attacker can pass specially crafted input to the application that is using the affected library, trigger a use-after-free error and execute arbitrary code on the system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
9) Improper input validation (CVE-ID: CVE-2022-21626)
The vulnerability allows a remote non-authenticated attacker to perform service disruption.
The vulnerability exists due to improper input validation within the Security component in Oracle GraalVM Enterprise Edition. A remote non-authenticated attacker can exploit this vulnerability to perform service disruption.
