Description
This security bulletin contains information about 9 vulnerabilities.
1) Out-of-bounds read (CVE-ID: CVE-2020-10037)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/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 a boundary condition. A remote attacker can perform a flood attack against the web server, trigger out-of-bounds read error and read contents of memory on the system.
2) Missing Authentication for Critical Function (CVE-ID: CVE-2020-10038)
CWE-ID: CWE-306 - Missing Authentication for Critical Function
CVSSv4: 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/E:U/U:Amber
The vulnerability allows a remote attacker to execute arbitrary commands on the target system.
The vulnerability exists due missing authentication for critical function. A remote attacker with access to the device’s web server can execute administrative commands without authentication.
3) Missing Encryption of Sensitive Data (CVE-ID: CVE-2020-10039)
CWE-ID: CWE-311 - Missing Encryption of Sensitive Data
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/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 the target system.
The vulnerability exists due to missing encryption of sensitive data. A remote attacker in a privileged network position between a legitimate user and the web server can conduct a man-in-the-middle attack and gain read and write access to the transmitted data.
4) Use of Password Hash With Insufficient Computational Effort (CVE-ID: CVE-2020-10040)
CWE-ID: CWE-916 - Use of Password Hash With Insufficient Computational Effort
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local attacker to access sensitive information on the target system.
The vulnerability exists due to usage of password hash with insufficient computational effort. A local attacker can retrieve passwords in clear text.
5) Stored cross-site scripting (CVE-ID: CVE-2020-10041)
CWE-ID: CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N/E:U/U:Clear
The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of user-supplied data in different locations of the web application. A remote attacker can inject and execute arbitrary HTML and script code in user's browser in context of vulnerable website.
Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
6) Buffer overflow (CVE-ID: CVE-2020-10042)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: 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/E:U/U:Amber
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error. A remote attacker can trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
7) Cross-site scripting (CVE-ID: CVE-2020-10043)
CWE-ID: CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N/E:U/U:Clear
The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of user-supplied data. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.
Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
8) Missing Authentication for Critical Function (CVE-ID: CVE-2020-10044)
CWE-ID: CWE-306 - Missing Authentication for Critical Function
CVSSv4: 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/E:U/U:Amber
The vulnerability allows a remote attacker to compromise the targte system.
The vulnerability exists due missing authentication for critical function. A remote attacker can install specially crafted firmware on the device.
9) Authentication Bypass by Capture-replay (CVE-ID: CVE-2020-10045)
CWE-ID: CWE-294 - Authentication Bypass by Capture-replay
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to bypass authentication on the target system.
The vulnerability exists due to improper authentication process. A remote attacker can replay authentication traffic and gain access to protected areas of the web application.
