Unisys WebPerfect Image Suite 3.0 NTLMv2 Hash Leakage via .NET Remoting

Unisys WebPerfect Image Suite versions 3.0.3960.22810 and 3.0.3960.22604 expose a deprecated .NET Remoting TCP channel that allows remote unauthenticated attackers to leak NTLMv2 machine-account hashes by supplying a Windows UNC path as a target file argument through object-unmarshalling techniques. Attackers can capture the leaked NTLMv2 hash and relay it to other hosts to achieve privilege escalation or lateral movement depending on network configuration and patch level.

Unisys WebPerfect Image Suite 3.0 NTLMv2 Hash Leakage via WCF SOAP

Unisys WebPerfect Image Suite versions 3.0.3960.22810 and 3.0.3960.22604 expose an unauthenticated WCF SOAP endpoint on TCP port 1208 that accepts unsanitized file paths in the ReadLicense action's LFName parameter, allowing remote attackers to trigger SMB connections and leak NTLMv2 machine-account hashes. Attackers can submit crafted SOAP requests with UNC paths to force the server to initiate outbound SMB connections, exposing authentication credentials that may be relayed for privilege escalation or lateral movement within the network.

Stack-based buffer overflow in mnet.exe in Unisys Business Information Server (BIS) 10 and 10.1 on Windows allows remote attackers to execute arbitrary code via a crafted TCP packet.

The dynamic initialization feature of the ClearPath MCP environment allows remote attackers to cause a denial of service (crash) via a TCP port scan using a tool such as nmap.

Unisys Data Exchange Management Studio before 6.0.IC2 and 7.x before 7.0.IC1 doesn't have an Anti-CSRF token to authenticate the POST request. Thus, a cross-site request forgery attack could occur.

An issue discovered in Unisys Stealth 5.3.062.0 allows attackers to view sensitive information via the Enterprise ManagementInstaller_msi.log file.

Unquoted Windows search path vulnerability in the guest service in Unisys s-Par before 4.4.20 allows local users to gain privileges via a Trojan horse executable file in the %SYSTEMDRIVE% directory, as demonstrated by program.exe.

Unisys Libra 64xx and 84xx and FS601 class systems with MCP-FIRMWARE before 43.211 allow remote authenticated users to cause a denial of service (program crash) or have unspecified other impact via vectors related to incorrect literal handling, which trigger CPM stack corruption.

The TCP/IP networking module in Unisys ClearPath MCP systems with TCP-IP-SW 57.1 before 57.152, 58.1 before 58.142, or 59.1 before 59.172, when running a TLS 1.2 service, allows remote attackers to cause a denial of service (network connectivity disruption) via a client hello with a signature_algorithms extension above those defined in RFC 5246, which triggers a full memory dump.

The mobiGate App for Android version 2.2.1.2 and earlier and mobiGate App for iOS version 2.2.4.1 and earlier do not verify X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate.

Unisys Libra 43xx, 63xx, and 83xx, and FS600 class systems with MCP-FIRMWARE 40.0 before 40.0IC4 Build 270 might allow remote authenticated users to cause a denial of service (data corruption or system crash) via vectors related to using program operators during EPSILON (level 5) based codefiles at peak memory usage, which triggers CPM stack corruption.

Unisys ClearPath MCP TCP/IP Networking Services 59.1, 60.0, and 62.0 has an Infinite Loop.

Unisys OS 2200 Messaging Integration Services (NTSI) 7R3B IC3 and IC4, 7R3C, and 7R3D has an Incorrect Implementation of an Authentication Algorithm. An LDAP password is not properly validated.

Unisys Cargo Mobile Application before 1.2.29 uses cleartext to store sensitive information, which might be revealed in a backup. The issue is addressed by ensuring that the allowBackup flag (in the manifest) is False.

In Unisys Stealth (core) before 6.0.025.0, the Keycloak password is stored in a recoverable format that might be accessible by a local attacker, who could gain access to the Management Server and change the Stealth configuration.

Unisys Stealth 5.1 before 5.1.025.0 and 6.0 before 6.0.055.0 has an unquoted Windows search path for a scheduled task. An unintended executable might run.

Unisys Stealth (core) 5.x before 5.0.048.0, 5.1.x before 5.1.017.0, and 6.x before 6.0.037.0 stores passwords in a recoverable format.

Unisys Data Exchange Management Studio through 5.0.34 doesn't sanitize the input to a HTML document field. This could be used for an XSS attack.

Unisys Stealth(core) before 4.0.134 stores passwords in a recoverable format. Therefore, a search of Enterprise Manager can potentially reveal credentials.

Unisys ALGOL Compiler 58.1 before 58.1a.15, 59.1 before 59.1a.9, and 60.0 before 60.0a.5 can emit invalid code sequences under rare circumstances related to syntax. The resulting code could, for example, trigger a system fault or adversely affect confidentiality, integrity, and availability.
