CVE-2025-34108
Published: 15 July 2025
Summary
CVE-2025-34108 is a high-severity Improper Input Validation (CWE-20) vulnerability. Its CVSS base score is 8.6 (High).
Operationally, ranked in the top 1.3% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
A stack-based buffer overflow vulnerability exists in the login functionality of Disk Pulse Enterprise version 9.0.34. The flaw occurs when the application processes an overly long username parameter in an HTTP POST request sent to the /login endpoint, resulting in uncontrolled data written to a buffer in the libspp.dll component. The issue is tracked under CWE-20 and CWE-121 and carries a CVSS 4.0 score of 8.6.
An unauthenticated attacker can exploit the condition by submitting a crafted POST request over the network. Successful overflow leads to arbitrary code execution with SYSTEM-level privileges on the affected host. The CVSS vector indicates the attack requires no privileges but does involve user interaction.
Public exploit code for the vulnerability is available in Metasploit, Exploit-DB, and related repositories, and the current EPSS score of 0.7048 reflects substantial exploitation interest. No mitigation details are provided in the available references.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Security testing and developer training directly verify and enforce proper input validation, reducing exploitability of injection and malformed-data weaknesses.
Security testing and evaluation at multiple SDLC stages directly detects missing or flawed input validation, with the required remediation process ensuring fixes are applied.
Directly implements checks on information inputs to reject invalid data before processing.
Spam protection mechanisms perform filtering and detection on inbound/outbound messages, directly compensating for missing or weak input validation of unsolicited content.
