Description

This security bulletin contains information about 3 vulnerabilities.


1) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2011-5058)

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote non-authenticated attacker to manipulate or delete data.

The CmbWebserver.dll module of the Control service in 3S CoDeSys 3.4 SP4 Patch 2 allows remote attackers to create arbitrary directories under the web root by specifying a non-existent directory using (backslash) characters in an HTTP GET request.


2) Heap-based buffer overflow (CVE-ID: CVE-2011-5008)

CWE-ID: CWE-122 - Heap-based Buffer Overflow

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in Integer overflow in the GatewayService component in 3S CoDeSys 3.4 SP4 Patch 2. A remote attacker can use a large size value in the packet header to trigger heap-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


3) NULL pointer dereference (CVE-ID: CVE-2011-5009)

CWE-ID: CWE-476 - NULL Pointer Dereference

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:P/U:Green


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error. A remote attacker can trigger denial of service conditions via (1) a crafted Content-Length in an HTTP POST or (2) an invalid HTTP request method.
