Description

This security bulletin contains information about 4 vulnerabilities.

1) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2019-10393)

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

CVSSv4: 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/E:U/U:Green

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to improper handling of method names in method call expressions. A remote authenticated attacker can specify and run sandboxed scripts to execute arbitrary code the target system.

2) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2019-10394)

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

CVSSv4: 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/E:U/U:Green

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to improper handling of property names in property expressions on the left-hand side of assignment expressions. A remote authenticated attacker can specify and run sandboxed scripts to execute arbitrary code the target system.

3) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2019-10399)

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

CVSSv4: 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/E:U/U:Green

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to improper handling of property names in property expressions in increment and decrement expressions. A remote authenticated attacker can specify and run sandboxed scripts to execute arbitrary code the target system.

4) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2019-10400)

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

CVSSv4: 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/E:U/U:Green

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to improper handling of subexpressions in increment and decrement expressions not involving actual assignment allowed. A remote authenticated attacker can specify and run sandboxed scripts to execute arbitrary code the target system.
