Description
This security bulletin contains information about 6 vulnerabilities.
1) Spoofing attack (CVE-ID: CVE-2023-25730)
CWE-ID: CWE-451 - User Interface (UI) Misrepresentation of Critical Information (Clickjacking, spoofing)
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to the possibility of screen hijacking. A background script invoking requestFullscreen and then blocking the main thread could force the browser into fullscreen mode indefinitely, resulting in potential user confusion or spoofing attacks.
2) Insufficient UI Warning of Dangerous Operations (CVE-ID: CVE-2023-25729)
CWE-ID: CWE-357 - Insufficient UI Warning of Dangerous Operations
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to missing permissions prompts for opening external schemes were only shown for ContentPrincipals. A malicious extension can open external schemes without user interaction via ExpandedPrincipals and perform other potentially dangerous actions, such as downloading files or interacting with software already installed on the system.
3) Input validation error (CVE-ID: CVE-2023-25742)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input in Web Crypto ImportKey when importing SPKI RSA public key as ECDSA P-256. A remote attacker can trick the victim to import the public key and crash the browser tab.
4) Security features bypass (CVE-ID: CVE-2023-25734)
CWE-ID: CWE-254 - Security Features
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to an error when handling Windows .url shortcuts that are opened by the browser from the local filesystem. A remote attacker can trick the victim into launching a specially crafted shortcut that then initiates network requests from the operating system to the malicious server. A remote attacker can obtain potentially sensitive information including NTLM credentials.
Note, the vulnerability affects Windows installations only.
5) Out-of-bounds read (CVE-ID: CVE-2023-25738)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a missing validation of members of the DEVMODEW struct set by the printer device driver while printing web page in Windows. A remote attacker can trick the victim to print a specially crafted web page and crash the browser.
Note, the vulnerability affects Windows installations only.
6) Information disclosure (CVE-ID: CVE-2023-25728)
CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to the Content-Security-Policy-Report-Only header can leak a child iframe's unredacted URI when interaction with that iframe triggers a redirect. A remote attacker can gain access to potentially sensitive information.
