NVD · unedited
Honeywell Saia PG5 Controls Suite XML External Entity Processing Information Disclosure Vulnerability. This vulnerability allows remote attackers to disclose sensitive information on affected installations of Honeywell Saia PG5 Controls Suite. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of XML files. Due to the improper restriction of XML External Entity (XXE) references, a crafted document specifying a URI causes the XML parser to access the URI and embed the contents back into the XML document for further processing. An attacker can leverage this vulnerability to disclose information in the context of the current process. . Was ZDI-CAN-18591.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

The vulnerability is an XML External Entity (XXE) injection flaw in Honeywell Saia PG5 Controls Suite's XML parser. The parser does not properly restrict XXE references, allowing crafted XML files with malicious URI specifications to access internal resources and embed their contents back into the XML document for further processing, leading to information disclosure in the context of the current process.

MitigationDisable external entity processing in the XML parser configuration and implement secure XML parsing settings (such as disabling DTDs and external entities) to prevent XXE attacks.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Confirm Saia PG5 Controls Suite installation
    Check for the Saia PG5 installation directory, typically found under C:\Program Files\Honeywell\Saia PG5 or C:\Program Files (x86)\Honeywell\Saia PG5. Also check Windows Registry under HKEY_LOCAL_MACHINE\SOFTWARE\Honeywell\Saia PG5 for installation evidence.
    Affected if The product is present on the system and the XML parser is used to process untrusted XML files.
  2. Identify installed Saia PG5 version
    Locate the version information in the installation directory, typically in an About or Version file, or check the registry key for the installed version number.
    Affected if Any version number is returned, as the advisory states all versions are affected.
  3. Locate XML configuration or data files processed by Saia PG5
    Search the Saia PG5 installation directory and project directories for .xml files that may be parsed by the application. Common locations include project folders, config subdirectories, and data directories used by the controls suite.
    Affected if XML files exist in the Saia PG5 directories and are processed by the application.
  4. Inspect XML parser configuration for XXE protection
    Examine Saia PG5 configuration files, XML parser settings, or any documentation related to XML processing. Look for whether external entities and DTD processing are explicitly disabled in the parser configuration.
    Affected if The XML parser configuration does NOT explicitly disable external entities and DTD processing, or the configuration cannot be verified as secure.
  5. Review application logs for XML processing activity
    Check Saia PG5 logs or event logs for evidence of XML file processing. Look for parser initialization or XML-related operations that may indicate the vulnerable code path is exercised.
    Affected if The application processes XML files during normal operation and the parser settings cannot be verified as secure.

If Saia PG5 Controls Suite is installed and processes XML files without secure parser configuration that explicitly disables external entities and DTDs, the environment is likely vulnerable to CVE-2023-51602 XXE injection.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Disable external entity processing in the XML parser configuration and implement secure XML parsing settings (such as disabling DTDs and external entities) to prevent XXE attacks.
