Description
This security bulletin contains information about 11 secuirty vulnerabilities.
1) Resource exhaustion (CVE-ID: CVE-2021-21341)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
2) Deserialization of Untrusted Data (CVE-ID: CVE-2021-21342)
The vulnerability allows a remote attacker to perform SSRF attacks.
The vulnerability exists due to insecure input validation when processing serialized data. A remote attacker can pass specially crafted data to the application and perform SSRF attack.
3) Deserialization of Untrusted Data (CVE-ID: CVE-2021-21343)
The vulnerability allows a remote attacker to delete arbitrary files.
The vulnerability exists due to insecure input validation when processing serialized data where the processed stream at unmarshalling time contains type information to recreate the formerly written objects. A remote attacker can pass specially crafted data to the application and delete arbitrary files.
4) Deserialization of Untrusted Data (CVE-ID: CVE-2021-21344)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to insecure input validation when processing serialized data. A remote attacker can pass specially crafted data to the application and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
5) Deserialization of Untrusted Data (CVE-ID: CVE-2021-21345)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to insecure input validation when processing serialized data. A remote attacker can pass specially crafted data to the application and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
6) Deserialization of Untrusted Data (CVE-ID: CVE-2021-21346)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to insecure input validation when processing serialized data. A remote attacker can pass specially crafted data to the application and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
7) Deserialization of Untrusted Data (CVE-ID: CVE-2021-21347)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to insecure input validation when processing serialized data. A remote attacker can pass specially crafted data to the application and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
8) Resource exhaustion (CVE-ID: CVE-2021-21348)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
9) Deserialization of Untrusted Data (CVE-ID: CVE-2021-21349)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to insecure input validation when processing serialized data. A remote attacker can pass specially crafted data to the application and gain access to sensitive information.
10) Deserialization of Untrusted Data (CVE-ID: CVE-2021-21350)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to insecure input validation when processing serialized data. A remote attacker can pass specially crafted data to the application and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
11) Deserialization of Untrusted Data (CVE-ID: CVE-2021-21351)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to insecure input validation when processing serialized data. A remote attacker can pass specially crafted data to the application and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
