Summary
Ein entfernter, anonymer Angreifer kann mehrere Schwachstellen in ABB AC-500 ausnutzen, um beliebigen Programmcode auszuführen, Informationen offenzulegen, einen Denial of Service Zustand herbeizuführen oder Dateien zu manipulieren.
Product
Die ABB AC-500 ist eine speicherprogrammierbare Steuerung (SPS).
Vulnerabilities 12
-
High 8.8
CODESYS Runtime System prone to heap based buffer overflow
In multiple CODESYS products, a low privileged remote attacker may craft a request, which may cause a heap-based buffer overflow, resulting in a denial-of-service condition or memory overwrite. User interaction is not required.
-
High 8.8
CODESYS runtime system prone to denial of service due to Unexpected Sign Extension
In multiple CODESYS products, a remote attacker may craft a request which may cause an unexpected sign extension, resulting in a denial-of-service condition or memory overwrite.
-
High 8.8
CODESYS runtime system prone to directory acces
In multiple CODESYS products, file download and upload function allows access to internal files in the working directory e.g. firmware files of the PLC. All requests are processed on the controller only if no level 1 password is configured on the controller o…
-
High 8.1
CODESYS V2 runtime: out-of-bounds read or write access may result in denial-of-service
A crafted request with invalid offsets may cause an out-of-bounds read or write access in CODESYS V2 Runtime Toolkit 32 Bit full and PLCWinNT prior to versions V2.4.7.56, resulting in a denial-of-service condition or local memory overwrite.
-
High 8.1
CODESYS runtime system prone to file deletion due to improper error handling
Multiple products of CODESYS implement a improper error handling. A low privilege remote attacker may craft a request, which is not properly processed by the error handling. In consequence, the file referenced by the request could be deleted. User interaction…
-
High 8.1
CODESYS runtime system prone to denial of service due to use of out of range pointer
Multiple CODESYS Products are prone to a out-of bounds read or write access. A low privileged remote attacker may craft a request with invalid offset, which can cause an out-of-bounds read or write access, resulting in denial-of-service condition or local mem…
-
High 7.5
Insecure transmission of credentials
In the CODESYS Development System multiple components in multiple versions transmit the passwords for the communication between clients and servers unprotected.
-
Medium 6.5
Codesys runtime systems: Access of uninitialised pointer lead to denial of service.
In multiple CODESYS products, a low privileged remote attacker may craft a request that cause a read access to an uninitialized pointer, resulting in a denial-of-service. User interaction is not required.
-
Medium 6.5
CODESYS runtime system prone to denial of service due to out of bounds read
In multiple CODESYS products, a low privileged remote attacker may craft a request, which cause an out-of-bounds read, resulting in a denial-of-service condition. User Interaction is not required.
-
Medium 6.5
CODESYS runtime system prone to denial of service due to buffer copy
Multiple CODESYS products are affected to a buffer overflow.A low privileged remote attacker may craft a request, which can cause a buffer copy without checking the size of the service, resulting in a denial-of-service condition. User Interaction is not requi…
-
Medium 6.5
CODESYS runtime system prone to denial of service due to buffer over read
Multiple CODESYS Products are prone to a buffer over read. A low privileged remote attacker may craft a request with an invalid offset, which can cause an internal buffer over-read, resulting in a denial-of-service condition. User interaction is not required.
-
Medium 5.3
Improper Check for Unusual or Exceptional Conditions
Improper Input Validation vulnerability in ABB AC500 V2 PM5xx allows Client-Server Protocol Manipulation.This issue affects AC500 V2: from 2.0.0 before 2.8.6.
