EXECUTIVE SUMMARY CVSS v4 8.5 ATTENTION: Exploitable remotely/low attack complexity Vendor: Ocean Data Systems Equipment: Dream Report 2023 Vulnerabilities: Path Traversal, Incorrect Permission Assignment for Critical Resource 2. RISK EVALUATION Successful exploitation of these vulnerabilities could allow an attacker to perform remote code execution or escalate their privileges and cause a denial-of-service condition. 3. TECHNICAL DETAILS 3.1 AFFECTED PRODUCTS The following components of Ocean Data Systems Dream Report, a report generating and delivery software, are affected: Dream Report 2023: Version 23.0.17795.1010 and prior AVEVA Reports for Operations 2023: Version 23.0.17795.1010 3.2 Vulnerability Overview 3.2.1 IMPROPER LIMITATION OF A PATHNAME TO A RESTRICTED DIRECTORY ('PATH TRAVERSAL') CWE-22 In Ocean Data Systems Dream Report, a path traversal vulnerability could allow an attacker to perform remote code execution through the injection of a malicious dynamic-link...

**According to the CVSS metric, the attack vector is network (AV:N) and the user interaction is required (UI:R). What is the target context of the remote code execution?** This attack requires an admin user on the client to connect to a malicious server, and that could allow the attacker to gain code execution on the client.

**How could an attacker exploit this vulnerability?** Exploitation requires the victim to open a malicious Microsoft Office Project file on a system where the Block macros from running in Office files from the Internet policy is disabled and VBA Macro Notification Settings are not enabled allowing the attacker to perform remote code execution. * In an email attack scenario, an attacker could send the malicious file to the victim and convince them to open the file. * In a web-based attack scenario, an attacker could host a website (or leverage a compromised website that accepts or hosts user-provided content) containing a malicious file designed to exploit the vulnerability. An attacker would have no way to force the victim to visit the website. Instead, an attacker would have to convince the victim to click a link, typically by way of an enticement in an email or instant message, and then convince them to open the malicious file.

**How could an attacker exploit this vulnerability?** An authenticated attacker with permissions to execute commands on the Azure CycleCloud instance could send a specially crafted request that returns the storage account credentials and runtime data. The attacker can then use the comprised credentials to access the underlying storage resources and upload malicious scripts which will be executed as Root, enabling remote code execution to be performed on any cluster in the CycleCloud instance.

**According to the CVSS metric, successful exploitation could lead to a scope change (S:C). What does this mean for this vulnerability?** This vulnerability could lead to the attacker gaining the ability to interact with other tenant’s applications and content.

**According to the CVSS metric, privileges required is high (PR:H). What does that mean for this vulnerability?** To successfully exploit this vulnerability, an attacker or the targeted user would need to achieve a high level of control over a machine, as the attack requires access to processes typically restricted from average users. Essentially, the exploitation necessitates elevated privileges on the compromised machine due to the requirement of manipulating processes beyond the reach of standard user permissions.

**According to the CVSS metric, the attack vector is physical (AV:P). What does that mean for this vulnerability?** To exploit this vulnerability, an unauthenticated attacker needs to physically connect a malicious USB device to the victim's machine

**According to the CVSS metric, the attack vector is local (AV:L). Why does the CVE title indicate that this is a remote code execution?** The word **Remote** in the title refers to the location of the attacker. This type of exploit is sometimes referred to as Arbitrary Code Execution (ACE). The attack itself is carried out locally. This means an attacker or victim needs to execute code from the local machine to exploit the vulnerability.

**According to the CVSS metric, the attack vector is local (AV:L). Why does the CVE title indicate that this is a remote code execution?** The word **Remote** in the title refers to the location of the attacker. This type of exploit is sometimes referred to as Arbitrary Code Execution (ACE). The attack itself is carried out locally. For example, when the score indicates that the **Attack Vector** is **Local** and **User Interaction** is **Required**, this could describe an exploit in which an attacker, through social engineering, convinces a victim to download and open a specially crafted file from a website which leads to a local attack on their computer.
