Description
This security bulletin contains information about 6 secuirty vulnerabilities.
1) Modification of assumed-immutable data (CVE-ID: CVE-2021-37177)
The vulnerability allows a remote attacker to bypass certain security restrictions.
The vulnerability exists due to application does not perform validation of the attacker-controlled data, assuming that data is valid and safe. A remote attacker on the local network can manipulate with the status provided by the syslog clients managed by the affected software.
2) Improper access control (CVE-ID: CVE-2021-37183)
The vulnerability allows a remote attacker to gain unauthorized access to otherwise restricted functionality.
The vulnerability exists due to the affected software allows sending send-to-sleep notifications to the managed devices. A remote attacker on the local network can cause a denial of service condition on the target system.
3) Information disclosure (CVE-ID: CVE-2021-37190)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output by the application. A remote attacker on the local network can gain unauthorized access to sensitive information on the system.
4) Improper control of interaction frequency (CVE-ID: CVE-2021-37191)
The vulnerability allows a remote attacker to gain access to sensitive information on the target system.
The vulnerability exists due to the affected software lacks brute force protection. A remote attacker on the local network can brute force the usernames from the affected software.
5) Information disclosure (CVE-ID: CVE-2021-37192)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output by the application. A remote attacker on the local network can gain unauthorized access to sensitive information on the system.
6) Modification of assumed-immutable data (CVE-ID: CVE-2021-37193)
The vulnerability allows a remote attacker to bypass certain security restrictions.
The vulnerability exists due to application does not perform validation of the attacker-controlled data, assuming that data is valid and safe. A remote attacker on the local network can manipulate certain parameters and set a valid user of the affected software as invalid (or vice-versa).
