Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
EUVDB-ID: #VU78977
Risk: High
CVSSv3.1: 7.9 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-3823
CWE-ID:
CWE-611 - Improper Restriction of XML External Entity Reference ('XXE')
Exploit availability: No
DescriptionThe 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.
MitigationUpdate php7.4 package to version 7.4.33-1+deb11u5.
Vulnerable software versionsDebian Linux: All versions
php7.4 (Debian package): before 7.4.33-1+deb11u5

EUVDB-ID: #VU78978
Risk: Critical
CVSSv3.1: 7.4 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:L/E:H/RL:O/RC:C]
CVE-ID: CVE-2023-3824
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: Yes
DescriptionThe 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.
MitigationUpdate php7.4 package to version 7.4.33-1+deb11u5.

EUVDB-ID: #VU88483
Risk: Low
CVSSv3.1: 3.7 [CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2024-2756
CWE-ID:
CWE-254 - Security Features
Exploit availability: No
DescriptionThe 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).
Update php7.4 package to version 7.4.33-1+deb11u5.

CVE-ID: CVE-2024-3096
CWE-ID:
CWE-287 - Improper Authentication
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to bypass authentication process.
