Description

This security bulletin contains information about 4 vulnerabilities.


1) Arbitrary file upload (CVE-ID: CVE-2019-13359)

CWE-ID: CWE-434 - Unrestricted Upload of File with Dangerous Type

CVSSv4: 7.7 [CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote authenticated user to execute arbitrary code.

In CentOS-WebPanel.com (aka CWP) CentOS Web Panel 0.9.8.836, a cwpsrv-xxx cookie allows a normal user to craft and upload a session file to the /tmp directory, and use it to become the root user.


2) Improper Authentication (CVE-ID: CVE-2019-13360)

CWE-ID: CWE-287 - Improper Authentication

CVSSv4: 9.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

In CentOS-WebPanel.com (aka CWP) CentOS Web Panel 0.9.8.836, remote attackers can bypass authentication in the login process by leveraging knowledge of a valid username.


3) Information disclosure (CVE-ID: CVE-2019-13383)

CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor

CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.

In CentOS-WebPanel.com (aka CWP) CentOS Web Panel 0.9.8.846, the Login process allows attackers to check whether a username is valid by reading the HTTP response.


4) Improper Authentication (CVE-ID: CVE-2019-13605)

CWE-ID: CWE-287 - Improper Authentication

CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote authenticated user to execute arbitrary code.

In CentOS-WebPanel.com (aka CWP) CentOS Web Panel 0.9.8.838 to 0.9.8.846, remote attackers can bypass authentication in the login process by leveraging the knowledge of a valid username. The attacker must defeat an encoding that is not equivalent to base64, and thus this is different from CVE-2019-13360.
