Description
This security bulletin contains information about 10 vulnerabilities.
1) Information disclosure (CVE-ID: CVE-2020-1857)
CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor
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 improper processing of some data. A local user can exploit this vulnerability through a series of operations and gain unauthorized access to sensitive information on the system.
2) Memory leak (CVE-ID: CVE-2020-1813)
CWE-ID: CWE-401 - Missing release of memory after effective lifetime
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to perform (DoS) attack on the target system.
The vulnerability exists due to the affected software does not sufficiently track and release allocated memory while parse certain message. A remote authenticated attacker can trigger memory consumption and cause a denial of service condition.
3) Out-of-bounds read (CVE-ID: CVE-2020-1830)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/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 boundary condition when IPSec Module handing a specific message. A remote attacker can send specific message, trigger 1 byte out-of-bounds read error and compromise normal service.
4) Input validation error (CVE-ID: CVE-2020-1828)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
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 when the IPSec module does not validate a field in a specific message. A remote attacker can send a specially crafted message, cause out-of-bound read and compromise normal service.
5) Input validation error (CVE-ID: CVE-2020-1814)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
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 when processing specific IPSEC packets. A remote attacker can send a specially crafted IPSEC packet to affected devices and cause the IPSEC function of the affected device abnormal.
6) Input validation error (CVE-ID: CVE-2020-1816)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper processing of specific IPSEC packets. A remote attacker can send specially crafted IPSEC packets to affected devices and cause the IPSEC function of the affected device abnormal.
7) Memory leak (CVE-ID: CVE-2020-1815)
CWE-ID: CWE-401 - Missing release of memory after effective lifetime
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to perform DoS attack on the target system.
The vulnerability exists due to the affected software does not sufficiently track and release allocated memory while parse certain message. A remote authenticated attacker can send specially crafted message, consume remaining memory and cause memory exhaust.
8) Improper access control (CVE-ID: CVE-2020-1860)
CWE-ID: CWE-284 - Improper Access Control
CVSSv4: CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to gain unauthorized access to otherwise restricted functionality.
The vulnerability exists due to improper access restrictions. A remote attacker on the local network can bypass implemented security restrictions and directly access the Internet.
9) Access of Uninitialized Pointer (CVE-ID: CVE-2020-1877)
CWE-ID: CWE-824 - Access of Uninitialized Pointer
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:P/PR:H/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to the affected software system access an invalid pointer when administrator log in to the device and performs some operations. A local administrator can cause certain process reboot.
10) Out-of-bounds read (CVE-ID: CVE-2020-1876)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/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 boundary condition when processing packets. A remote attacker on the local network can send a specially crafted packet with specific parameter, trigger out-of-bounds read error and cause the device reboot.
