Description
This security bulletin contains information about 12 secuirty vulnerabilities.
1) Out-of-bounds write (CVE-ID: CVE-2023-0568)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing untrusted input in fopen_wrappers.c. A remote attacker can pass a specially crafted filename to the affected application, trigger a one-byte buffer overflow and crash the application or potentially execute arbitrary code.
2) Use of insufficiently random values (CVE-ID: CVE-2023-0567)
The vulnerability allows a remote attacker to bypass authentication.
The vulnerability exists due to an error within the Password_verify() function, which always returns true with some hashes. A remote attacker can bypass authentication process and gain unauthorized access to the application.
3) Use of insufficiently random values (CVE-ID: CVE-2023-3247)
The vulnerability allows a remote attacker to bypass authentication.
The vulnerability exists due to a missing error check and insufficient random bytes in HTTP Digest authentication for SOAP. A remote attacker can perform a brute-force attack and bypass authentication process.
4) XML External Entity injection (CVE-ID: CVE-2023-3823)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to insufficient validation of user-supplied XML input. A remote attacker can pass a specially crafted XML code to the affected application and view contents of arbitrary files on the system or initiate requests to external systems.
Successful exploitation of the vulnerability may allow an attacker to view contents of arbitrary file on the server or perform network scanning of internal and external infrastructure.
5) Buffer overflow (CVE-ID: CVE-2023-3824)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the phar_dir_read() function. A remote attacker can force the application to open a specially crafted .phar archive, trigger memory corruption and execute arbitrary code on the target system.
6) Security features bypass (CVE-ID: CVE-2022-31629)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to the way PHP handles HTTP variable names. A remote attacker can set a standard insecure cookie in the victim's browser which is treated as a `__Host-` or `__Secure-` cookie by PHP applications.
7) Security features bypass (CVE-ID: CVE-2024-2756)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to the way PHP handles HTTP variable names. A remote attacker can set a standard insecure cookie in the victim's browser which is treated as a `__Host-` or `__Secure-` cookie by PHP applications.
Note, the vulnerability exists due to incomplete fix for #VU67756 (CVE-2022-31629).
8) Improper Authentication (CVE-ID: CVE-2024-3096)
The vulnerability allows a remote attacker to bypass authentication process.
The vulnerability exists due to an error in within the password_verify() function, which can erroneously return true. A remote attacker can bypass implemented authentication based on the vulnerable function and gain unauthorized access to the web application.
9) Input validation error (CVE-ID: CVE-2024-5458)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to insufficient validation of user-supplied input when parsing URL. A remote attacker can bypass the filter_var FILTER_VALIDATE_URL checks.
10) Input validation error (CVE-ID: CVE-2024-8925)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to insufficient validation of user-supplied input when parsing multipart form data. A remote attacker can pass specially crafted input to the application and bypass implemented security restrictions.
11) Security features bypass (CVE-ID: CVE-2024-8927)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to environment variable collision, which can lead to cgi.force_redirect bypass. A remote attacker can bypass implemented security restriction and gain unauthorized access to the application.
12) Insufficient Logging (CVE-ID: CVE-2024-9026)
The vulnerability allows an attacker to alter log files.
The vulnerability exists due to an unspecified error, which can lead to logs from child processes to be altered.
