CVSS v3.1 |
| A race condition vulnerability exists where an authenticated, local attacker on a Windows Nessus host could modify installation parameters at installation time, which could lead to the execution of arbitrary code on the Nessus host |
| When installing Nessus to a directory outside of the default location on a Windows host, Nessus versions prior to 10.7.3 did not enforce secure permissions for sub-directories. This could allow for local privilege escalation if users had not secured the directories in the non-default installation location. |
| In Nessus versions prior to 10.8.4, a non-authenticated attacker could alter Nessus logging entries by manipulating http requests to the application. |
|
As a part of Tenable’s vulnerability disclosure program, a vulnerability in a Nessus plugin was identified and reported. This vulnerability could allow a malicious actor with sufficient permissions on a scan target to place a binary in a specific filesystem location, and abuse the impacted plugin in order to escalate privileges.

| When installing Nessus to a non-default location on a Windows host, Nessus versions prior to 10.8.4 did not enforce secure permissions for sub-directories. This could allow for local privilege escalation if users had not secured the directories in the non-default installation location. - CVE-2025-24914 |
| When installing Nessus Agent to a non-default location on a Windows host, Nessus Agent versions prior to 10.8.3 did not enforce secure permissions for sub-directories. This could allow for local privilege escalation if users had not secured the directories in the non-default installation location. |
| In Tenable Nessus versions prior to 10.8.5 on a Windows host, it was found that a non-administrative user could overwrite arbitrary local system files with log content at SYSTEM privilege. |
| In libexpat in Expat before 2.2.7, XML input including XML names that contain a large number of colons could make the XML parser consume a high amount of RAM and CPU resources while processing (enough to be usable for denial-of-service attacks). |
| Insufficiently Protected Credentials: An authenticated user with debug privileges can retrieve stored Nessus policy credentials from the “nessusd” process in cleartext via process dumping. The affected products are all versions of Nessus Essentials and Professional. The vulnerability allows an attacker to access credentials stored in Nessus scanners, potentially compromising its customers’ network of assets. |
| An authenticated attacker could read Nessus Debug Log file attachments from the web UI without having the correct privileges to do so. This may lead to the disclosure of information on the scan target and/or the Nessus scan to unauthorized parties able to reach the Nessus instance. |
| Expat (aka libexpat) before 2.4.4 has an integer overflow in the doProlog function. |
| Expat (aka libexpat) before 2.4.4 has a signed integer overflow in XML_GetBuffer, for configurations with a nonzero XML_CONTEXT_BYTES. |
| storeAtts in xmlparse.c in Expat (aka libexpat) before 2.4.3 has an integer overflow. |
| nextScaffoldPart in xmlparse.c in Expat (aka libexpat) before 2.4.3 has an integer overflow. |
| lookup in xmlparse.c in Expat (aka libexpat) before 2.4.3 has an integer overflow. |
| defineAttribute in xmlparse.c in Expat (aka libexpat) before 2.4.3 has an integer overflow. |
| build_model in xmlparse.c in Expat (aka libexpat) before 2.4.3 has an integer overflow. |
| addBinding in xmlparse.c in Expat (aka libexpat) before 2.4.3 has an integer overflow. |
| In doProlog in xmlparse.c in Expat (aka libexpat) before 2.4.3, an integer overflow exists for m_groupSize. |
| In Expat (aka libexpat) before 2.4.3, a left shift by 29 (or more) places in the storeAtts function in xmlparse.c can lead to realloc misbehavior (e.g., allocating too few bytes, or only freeing memory). |
