Mô tả CVE
Rockwell RSLogix 5000 Insufficiently Protected Credentials
Rockwell Automation RSLogix 5000 7 through 20.01, and 21.0, does not properly implement password protection for .ACD files (aka project files), which allows local users to obtain sensitive information or modify data via unspecified vectors.Giải pháp CVE
According to Rockwell Automation, new RSLogix 5000 versions, V20.03
and V21.03, have been released that address this vulnerability. These
releases include mitigations that enhance password protection.
Project files created in earlier affected RSLogix 5000 versions of
software must be opened, resaved, and then downloaded to the appropriate
controller to mitigate the risk associated with this discovered
vulnerability.
IMPORTANT: Files with protected content that have been opened and
update using enhanced software will no longer be compatible with earlier
versions of RSLogix 5000 software. For example, a V20.01 project file
with protected content that has been opened and resaved using V20.03
software can only be opened with V20.03 and higher versions of software.
Also, a V21.00 project file with protected content that has been opened
and resaved using V21.03 software can only be opened with V21.03 and
higher versions of software.
For the procedure to update project files, please refer to Rockwell Automation Knowledgebase AID:565204 available here: https://rockwellautomation.custhelp.com/app/answers/detail/a_id/565204 .
In addition to using current RSLogix 5000 software, Rockwell
Automation also recommends the following actions to all concerned
customers:
* Where possible, adopt a practice to track creation and distribution
of protected ACD files, including duplicates and derivatives that
contain protected content in the event that these files may need to be
found or potentially disposed of in the future.
* Where possible, securely archive protected ACD files or those that
contain protected content in a manner that prevents unauthorized access.
For instance, store protected ACD files in physical and logical
locations where access can be controlled and the files are stored in a
protected, potentially encrypted manner.
* Where possible, securely transmit protected ACD files or those that
contain protected content in a manner that prevents unauthorized access.
For instance, email protected ACD files only to known recipients and
encrypted the files such that only the target recipient can decrypt the
content.
* Where possible, restrict physical and network access to controllers
containing protected content only to authorized parties in order to help
prevent unauthorized uploading of protected material into an ACD file.
For some customers, FactoryTalk Security software may be a suitable
option to assist customers with applying a Role-based Access Control
(RBAC) solution to their system. FactoryTalk Security was integrated
into RSLogix 5000 Version 10.00.
* Where possible, use a unique and complex password for each routine
or Add-On Instruction desirable to protect, so as to reduce the risk
that multiple files and protected content could be compromised, should a
single password become learned.
* Where possible, adopt a password management practice to periodically
change passwords applied to routines and Add-On Instructions to help
mitigate the risk that a learned password may remain usable for an
extended period of time or indefinitely.

EPSS
EPSS là mô hình tính điểm dự đoán khả năng một lỗ hổng bị khai thác.
Điểm EPSS
Mô hình EPSS tạo ra điểm xác suất từ 0 đến 1 (0 đến 100%). Điểm càng cao, xác suất một lỗ hổng bị khai thác càng lớn.
Phân vị EPSS
Phân vị được dùng để xếp hạng CVE theo điểm EPSS. Ví dụ, một CVE ở phân vị thứ 95 theo điểm EPSS có nhiều khả năng bị khai thác hơn 95% CVE khác. Do đó, phân vị được dùng để so sánh điểm EPSS của một CVE với các CVE khác.
