Description
This security bulletin contains information about 9 vulnerabilities.
1) Cleartext storage of sensitive information (CVE-ID: CVE-2023-40724)
CWE-ID: CWE-312 - Cleartext Storage of Sensitive Information
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local user to gain access to potentially sensitive information.
The vulnerability exists due to user credentials are found in memory as plaintext. A local user can get access to user credentials.
2) Information Exposure Through an Error Message (CVE-ID: CVE-2023-40725)
CWE-ID: CWE-209 - Information Exposure Through an Error Message
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local attacker to gain access to potentially sensitive information.
The vulnerability exists due to affected application returns inconsistent error messages in response to invalid user credentials during login session. A local attacker can enumerate usernames, and identify valid usernames.
3) Information disclosure (CVE-ID: CVE-2023-40726)
CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/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 affected application server responds with sensitive information about the server. A remote user can directly access the database.
4) Improper Verification of Cryptographic Signature (CVE-ID: CVE-2023-40727)
CWE-ID: CWE-347 - Improper Verification of Cryptographic Signature
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local user to compromise the target system.
The vulnerability exists due to weak outdated application signing mechanism in the QMS.Mobile module. A local user can tamper the application code.
5) Information disclosure (CVE-ID: CVE-2023-40728)
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:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to the affected application stores sensitive application data in an external insecure storage wirhin the QMS.Mobile module. A remote attacker can alter content, leading to arbitrary code execution or denial of service (DoS) attack.
6) Cleartext transmission of sensitive information (CVE-ID: CVE-2023-40729)
CWE-ID: CWE-319 - Cleartext Transmission of Sensitive Information
CVSSv4: CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:A/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to software uses insecure communication channel to transmit sensitive information. A remote attacker with ability to intercept network traffic can gain access to sensitive data.
7) Improper access control (CVE-ID: CVE-2023-40730)
CWE-ID: CWE-284 - Improper Access Control
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to gain unauthorized access to otherwise restricted functionality.
The vulnerability exists due to improper access restrictions in the QMS.Mobile module. A remote user can access confidential information, perform administrative functions or perform a denial of service (DoS) attack.
8) Arbitrary file upload (CVE-ID: CVE-2023-40731)
CWE-ID: CWE-434 - Unrestricted Upload of File with Dangerous Type
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to insufficient validation of file during file upload. A remote user can upload a malicious file and execute it on the server.
9) Insufficient Session Expiration (CVE-ID: CVE-2023-40732)
CWE-ID: CWE-613 - Insufficient Session Expiration
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local user to gain access to sensitive information.
The vulnerability exists due to insufficient session expiration issue in the QMS.Mobile module. A local user can perform session hijacking attacks.
