Security Bulletin
This security bulletin contains information about 5 vulnerabilities.
1) Inefficient regular expression complexity
EUVDB-ID: #VU79318
Risk: Medium
CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-26117
CWE-ID:
CWE-1333 - Inefficient Regular Expression Complexity
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient input validation when processing untrusted input passed via the $resource service. A remote attacker can pass specially crafted data to the application and perform regular expression denial of service (ReDos) attack.
Install update from vendor's website.

3) Inefficient regular expression complexity
EUVDB-ID: #VU81699
Risk: Medium
CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-26118
CWE-ID:
CWE-1333 - Inefficient Regular Expression Complexity
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient input validation when processing untrusted input with a regular expressions in the input[url] functionality. A remote attacker can pass specially crafted data to the application and perform regular expression denial of service (ReDos) attack.

4) Cross-site scripting
EUVDB-ID: #VU87182
Risk: Medium
CVSSv3.1: 5.3 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-25869
CWE-ID:
CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Exploit availability: No
DescriptionThe disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of user-supplied data. A remote attacker can trick the victim to follow a specially crafted link 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.

EUVDB-ID: #VU87188
Risk: Medium
CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-25844
CWE-ID:
CWE-1333 - Inefficient Regular Expression Complexity
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to angular provides a custom locale rule that makes it possible to assign the parameter in posPre: ' '.repeat() of NUMBER_FORMATS.PATTERNS[1].posPre with a very high value. A remote attacker can pass specially crafted data to the application and perform regular expression denial of service (ReDos) attack.
