Vulnerabilities

Insider Threat Management (ITM) Server versions prior to 7.17.2 contain an authentication bypass vulnerability that allows unauthenticated users on an adjacent network to perform agent unregistration when the number of registered agents exceeds the licensed limit. Successful exploitation prevents the server from receiving new events from affected agents, resulting in a partial loss of integrity and availability with no impact to confidentiality.

Enterprise Protection contains an improper input validation vulnerability in attachment defense that allows an unauthenticated remote attacker to bypass attachment scanning security policy by sending a malicious S/MIME attachment with an opaque signature. When opened by a recipient in a downstream email client, the malicious attachment could cause partial loss of integrity and confidentiality to their system.

Proofpoint Enterprise Protection contains a vulnerability in the email delivery agent that allows an unauthenticated attacker to inject improperly encoded HTML into the email body of a message through the email subject. The vulnerability is caused by inappropriate encoding when rewriting the email before delivery.This issue affects Proofpoint Enterprise Protection: from 8.20.2 before patch 4809, from 8.20.0 before patch 4805, from 8.18.6 before patch 4804 and all other prior versions.

Proofpoint Enterprise Protection contains a stored XSS vulnerability in the AdminUI. An unauthenticated attacker can send a specially crafted email with HTML in the subject which triggers XSS when viewing quarantined messages. This issue affects Proofpoint Enterprise Protection: from 8.20.0 before patch 4796, from 8.18.6 before patch 4795 and all other prior versions.

An improper certification validation vulnerability in the Insider Threat Management (ITM) Agent for MacOS could be used by an anonymous actor on an adjacent network to establish a man-in-the-middle position between the agent and the ITM server after the agent has registered. All versions prior to 7.14.3.69 are affected. Agents for Windows, Linux, and Cloud are unaffected.

A missing authorization check in the MacOS agent configuration endpoint of the Insider Threat Management Server enables an anonymous attacker on an adjacent network to obtain sensitive information. Successful exploitation requires an attacker to first obtain a valid agent authentication token. All versions before 7.14.3 are affected.

An insecure filesystem permission in the Insider Threat Management Agent for Windows enables local unprivileged users to disrupt agent monitoring. All versions prior to 7.14.3 are affected. Agents for MacOS and Linux and Cloud are unaffected.

An information disclosure vulnerability in the faye endpoint in Proofpoint Threat Response / Threat Response Auto-Pull (PTR/TRAP) could be used by an attacker on an adjacent network to obtain credentials to integrated services via a man-in-the-middle position or cryptanalysis of the session traffic. An attacker could use these credentials to impersonate PTR/TRAP to these services. All versions prior to 5.10.0 are affected.

The webservices in Proofpoint Enterprise Protection (PPS/POD) contain a vulnerability that allows for an anonymous user to execute remote code through 'eval injection'. Exploitation requires network access to the webservices API, but such access is a non-standard configuration. This affects all versions 8.20.0 and below.

Proofpoint Enterprise Protection (PPS/PoD) contains a vulnerability which allows the pps user to escalate to root privileges due to unnecessary permissions. This affects all versions 8.19.0 and below.

The Admin Smart Search feature in Proofpoint Enterprise Protection (PPS/PoD) contains a stored cross-site scripting vulnerability that enables an anonymous email sender to gain admin privileges within the user interface. This affects all versions 8.19.0 and below.

Proofpoint Enterprise Protection before 18.8.0 allows a Bypass of a Security Control.

Proofpoint Insider Threat Management Agent for Windows relies on an inherently dangerous function that could enable an unprivileged local Windows user to run arbitrary code with SYSTEM privileges. All versions prior to 7.12.1 are affected. Agents for MacOS and Linux and Cloud are unaffected. Proofpoint has released fixed software version 7.12.1. The fixed software versions are available through the customer support portal.

Proofpoint Insider Threat Management Server contains a SQL injection vulnerability in the Web Console. The vulnerability exists due to improper input validation on the database name parameter required in certain unauthenticated APIs. A malicious URL visited by anyone with network access to the server could be used to blindly execute arbitrary SQL statements on the backend database. Version 7.12.0 and all versions prior to 7.11.2 are affected.

Proofpoint Enterprise Protection before 8.12.0-2108090000 allows security control bypass.

Proofpoint Spam Engine before 8.12.0-2106240000 has a Security Control Bypass.

Proofpoint Enterprise Protection (PPS/PoD) before 8.16.4 contains a vulnerability that could allow an attacker to deliver an email message with a malicious attachment that bypasses scanning and file-blocking rules. The vulnerability exists because messages with certain crafted and malformed multipart structures are not properly handled.

The Proofpoint Insider Threat Management Server (formerly ObserveIT Server) is missing an authorization check on several pages in the Web Console. This enables a view-only user to change any configuration setting and delete any registered agents. All versions before 7.11.1 are affected.

Insider Threat Management Windows Agent Local Privilege Escalation Vulnerability The Proofpoint Insider Threat Management (formerly ObserveIT) Agent for Windows before 7.4.3, 7.5.4, 7.6.5, 7.7.5, 7.8.4, 7.9.3, 7.10.2, and 7.11.0.25 as well as versions 7.3 and earlier is missing authentication for a critical function, which allows a local authenticated Windows user to run arbitrary commands with the privileges of the Windows SYSTEM user. Agents for MacOS, Linux, and ITM Cloud are not affected.

rcdsvc in the Proofpoint Insider Threat Management Windows Agent (formerly ObserveIT Windows Agent) before 7.9 allows remote authenticated users to execute arbitrary code as SYSTEM because of improper deserialization over named pipes.

The Proofpoint Insider Threat Management Server (formerly ObserveIT Server) before 7.9.1 contains a vulnerability in the ITM application server's WriteImage API. The vulnerability allows an anonymous remote attacker to execute arbitrary code with local administrator privileges. The vulnerability is caused by improper deserialization.

An issue was discovered in Proofpoint Email Protection through 2019-09-08. By collecting scores from Proofpoint email headers, it is possible to build a copy-cat Machine Learning Classification model and extract insights from this model. The insights gathered allow an attacker to craft emails that receive preferable scores, with a goal of delivering malicious emails.

A file-extension filtering vulnerability in Proofpoint Enterprise Protection (PPS / PoD), in the unpatched versions of PPS through 8.9.22 and 8.14.2 respectively, allows attackers to bypass protection mechanisms (related to extensions, MIME types, virus detection, and journal entries for transmitted files) by sending malformed (not RFC compliant) multipart email.
