Missing Authentication for Critical Function vulnerability in GE Vernova Enervista UR Setup application allows Authentication Bypass due to a missing SSH server authentication. Since the client connection is not authenticated, an attacker may perform a man-in-the-middle attack on the network.

Insufficient Verification of Data Authenticity vulnerability in GE Vernova UR IED family devices allows an authenticated user to install a modified firmware. The firmware signature verification is enforced only on the client-side dedicated software Enervista UR Setup, allowing the integration check to be bypassed.

CWE-282 "Improper Ownership Management" in GE Vernova EnerVista UR Setup allows Authentication Bypass.  The software's startup authentication can be disabled by altering a Windows registry setting that any user can modify.

Use of Hard-coded Credentials vulnerability in GE Vernova EnerVista UR Setup allows Privilege Escalation. The local user database is encrypted using an hardcoded password retrievable by an attacker analyzing the application code.

A CWE-15 "External Control of System or Configuration Setting" in GE Vernova UR IED family devices from version 7.0 up to 8.60 allows an attacker to provide input that establishes a TCP connection through a port forwarding. The lack of the IP address and port validation may allow the attacker to bypass firewall rules or to send malicious traffic in the network.

All versions of GE Digital CIMPLICITY that are not adhering to SDG guidance and accepting documents from untrusted sources are vulnerable to memory corruption issues due to insufficient input validation, including issues such as out-of-bounds reads and writes, use-after-free, stack-based buffer overflows, uninitialized pointers, and a heap-based buffer overflow. Successful exploitation could allow an attacker to execute arbitrary code.

A restricted desktop environment escape vulnerability exists in the Kiosk Mode functionality of affected devices. Specially crafted inputs can allow the user to escape the restricted environment, resulting in access to the underlying operating system. Affected devices include the following GE Ultrasound Products: Vivid products - all versions; LOGIQ - all versions not including LOGIQ 100 Pro; Voluson - all versions; Versana Essential - all versions; Invenia ABUS Scan station - all versions; Venue - all versions not including Venue 40 R1-3 and Venue 50 R4-5

In GE PACSystems RX3i CPE305/310 version 9.20 and prior, RX3i CPE330 version 9.21 and prior, RX3i CPE 400 version 9.30 and prior, PACSystems RSTi-EP CPE 100 all versions, and PACSystems CPU320/CRU320 RXi all versions, the device does not properly validate input, which could allow a remote attacker to send specially crafted packets causing the device to become unavailable.

A Stack-based Buffer Overflow issue was discovered in GE D60 Line Distance Relay devices running firmware Version 7.11 and prior. Multiple stack-based buffer overflow vulnerabilities have been identified, which may allow remote code execution.

An Improper Restriction of Operations within the Bounds of a Memory Buffer issue was discovered in GE D60 Line Distance Relay devices running firmware Version 7.11 and prior. The SSH functions of the device are vulnerable to buffer overflow conditions that may allow a remote attacker to execute arbitrary code on the device.

Directory traversal vulnerability in gefebt.exe in the WebView CimWeb components in GE Intelligent Platforms Proficy HMI/SCADA - CIMPLICITY through 8.2 SIM 24, and Proficy Process Systems with CIMPLICITY, allows remote attackers to execute arbitrary code via a crafted HTTP request, aka ZDI-CAN-1622.

Directory traversal vulnerability in CimWebServer.exe (aka the WebView component) in GE Intelligent Platforms Proficy HMI/SCADA - CIMPLICITY before 8.2 SIM 24, and Proficy Process Systems with CIMPLICITY, allows remote attackers to execute arbitrary code via a crafted message to TCP port 10212, aka ZDI-CAN-1623.

SSH 1.2.25, 1.2.23, and other versions, when used in in CBC (Cipher Block Chaining) or CFB (Cipher Feedback 64 bits) modes, allows remote attackers to insert arbitrary data into an existing stream between an SSH client and server by using a known plaintext attack and computing a valid CRC-32 checksum for the packet, aka the "SSH insertion attack."

A flaw was found in the way the DES/3DES cipher was used as part of the TLS/SSL protocol. A man-in-the-middle attacker could use this flaw to recover some plaintext data by capturing large amounts of encrypted traffic between TLS/SSL server and client if the communication used a DES/3DES based ciphersuite.

A new attack was discovered against TLS that allows an attacker to recover a limited amount of plaintext from a TLS connection when RC4 encryption is used. The attacks arise from statistical flaws in the keystream generated by the RC4 algorithm which become apparent in TLS ciphertexts when the same plaintext is repeatedly encrypted at a fixed location across many TLS sessions.

An issue was discovered in General Electric (GE) Proficy HMI/SCADA iFIX Version 5.8 SIM 13 and prior versions, Proficy HMI/SCADA CIMPLICITY Version 9.0 and prior versions, and Proficy Historian Version 6.0 and prior versions. An attacker may be able to retrieve user passwords if he or she has access to an authenticated session.

KEPServerEX does not properly validate certificates from clients which may allow unauthenticated users to connect.

ProficySCADA for iOS 5.0.25920 contains a denial of service vulnerability that allows attackers to crash the application by manipulating the password input field. Attackers can overwrite the password field with 257 bytes of repeated characters to trigger an application crash and prevent successful authentication.
