https://notcve.org/view.php?id=CVE-2023-32563
An unauthenticated attacker could achieve the code execution through a RemoteControl server. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Ivanti Avalanche. Authentication is not required to exploit this vulnerability. The specific flaw exists within the updateSkin method. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to execute code in the context of SYSTEM. • https://forums.ivanti.com/s/article/Avalanche-Vulnerabilities-Addressed-in-6-4-1?language=en_US https://twitter.com/wvuuuuuuuuuuuuu/status/1694956245742923939 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •

CVSS: 9.8EPSS: 1%CPEs: 1EXPL: 0CVE-2023-32567 – Ivanti Avalanche decodeToMap XML External Entity Processing Information Disclosure Vulnerability
https://notcve.org/view.php?id=CVE-2023-32567
Ivanti Avalanche decodeToMap XML External Entity Processing. Fixed in version 6.4.1.236 This vulnerability allows remote attackers to disclose sensitive information on affected installations of Ivanti Avalanche. Authentication is not required to exploit this vulnerability. The specific flaw exists within the decodeToMap method. 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 SYSTEM. • https://download.wavelink.com/Files/avalanche_v6.4.1.236_release_notes.txt • CWE-611: Improper Restriction of XML External Entity Reference •
