CVSS: 9.8EPSS: 5%CPEs: 1EXPL: 0CVE-2023-46265 – Ivanti Avalanche decode XML External Entity Processing Information Disclosure Vulnerability
https://notcve.org/view.php?id=CVE-2023-46265
An unauthenticated could abuse a XXE vulnerability in the Smart Device Server to leak data or perform a Server-Side Request Forgery (SSRF). Una persona no autenticada podría aprovechar una vulnerabilidad XXE en el Smart Device Server para filtrar datos o realizar Server-Side Request Forgery (SSRF). 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 decode 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. • https://download.wavelink.com/Files/avalanche_v6.4.2_release_notes.txt • CWE-611: Improper Restriction of XML External Entity Reference •
CVSS: 9.8EPSS: 1%CPEs: 2EXPL: 0CVE-2023-46257 – Ivanti Avalanche WLAvalancheService Stack-based Buffer Overflow Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2023-46257
An attacker sending specially crafted data packets to the Mobile Device Server can cause memory corruption which could result to a Denial of Service (DoS) or code execution. Un atacante que envía paquetes de datos especialmente manipulados a Mobile Device Server puede provocar daños en la memoria, lo que podría provocar una denegación de servicio (DoS) o la ejecución de código. 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 WLAvalancheService. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. • https://download.wavelink.com/Files/avalanche_v6.4.2_release_notes.txt • CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2023-46804
An attacker sending specially crafted data packets to the Mobile Device Server can cause memory corruption which could result to a Denial of Service (DoS). Un atacante que envía paquetes de datos especialmente manipulados a Mobile Device Server puede provocar daños en la memoria, lo que podría provocar una denegación de servicio (DoS). This vulnerability allows remote attackers to create a denial-of-service condition on affected installations of Ivanti Avalanche. Authentication is not required to exploit this vulnerability. The specific flaw exists within the WLAvalancheService. The issue results from the lack of proper validation of user-supplied data, which can result in an integer underflow before reading from memory. • https://download.wavelink.com/Files/avalanche_v6.4.2_release_notes.txt • CWE-787: Out-of-bounds Write •
