- Medium
- High
- Critical
Description
This security bulletin contains information about 8 secuirty vulnerabilities.
1) Stack-based buffer overflow (CVE-ID: CVE-2022-24313)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the IGSSDataServer process. A remote unauthenticated attacker can trigger stack-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
2) Out-of-bounds read (CVE-ID: CVE-2022-24314)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary condition within the IGSSdataServer.exe. A remote attacker can send a specially crafted message, trigger out-of-bounds read error and cause a denial of service condition on the system.
3) Integer overflow (CVE-ID: CVE-2022-24310)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow within the IGSSdataServer.exe. A remote attacker can send specially crafted messages, trigger integer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
4) Missing Authorization (CVE-ID: CVE-2022-24317)
The vulnerability allows a remote attacker to bypass authorization checks.
The vulnerability exists due to missing authorization within the IGSSDataServer process. A remote attacker can send a specially crafted message and cause information exposure.
5) Out-of-bounds read (CVE-ID: CVE-2022-24315)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary condition within the IGSSDataServer process. A remote attacker can send a specially crafted message, trigger out-of-bounds read error and cause a denial of service condition on the system.
6) Path traversal (CVE-ID: CVE-2022-24311)
The vulnerability allows a remote attacker to perform directory traversal attacks.
The vulnerability exists due to input validation error when processing directory traversal sequences within the IGSSDataServer process. A remote attacker can cause modification of an existing file by inserting at beginning of file or create a new file in the context of the Data Server.
7) Path traversal (CVE-ID: CVE-2022-24312)
The vulnerability allows a remote attacker to perform directory traversal attacks.
The vulnerability exists due to input validation error when processing directory traversal sequences within the IGSSDataServer process. A remote attacker can cause modification of an existing file by adding at end of file or create a new file in the context of the Data Server.
8) Improper Initialization (CVE-ID: CVE-2022-24316)
The vulnerability allows a remote attacker to gain access to sensitive information on the system.
The vulnerability exists due to improper initialization within the IGSSDataServer process. A remote attacker can send a specially crafted message and cause information exposure.
