Vendor: Cisco Product: Cisco Smart Software Manager On-Prem
Description
A vulnerability in the authentication system of Cisco Smart Software Manager On-Prem (SSM On-Prem) could allow an unauthenticated, remote attacker to change the password of any user, including administrative users. This vulnerability is due to improper implementation of the password-change process. An attacker could exploit this vulnerability by sending crafted HTTP requests to an affected device. A successful exploit could allow an attacker to access the web UI or API with the privileges of the compromised user.

Each milestone comes from a different source, so gaps between them are gaps in what those sources publish, not evidence that nothing happened. EPSS history for this CVE holds 175 points from 2024-07-20, tracked daily from 2026-09-09; earlier points are weekly, which dates a spike to within a week. Peak probability 91.5% on 2025-08-30.
Published Applicability
Check whether a specific version is affected →
What each source publishes about which product versions carry this vulnerability, kept as written rather than merged. Absence here means no source has published applicability data, not that nothing is affected.
Detection & Exploitation
Coverage across public collections only: Nuclei and OpenVAS NVT (scan);
Snort and Suricata ET Open (network); Sigma and YARA (host/SIEM);
Metasploit, Exploit-DB, public GitHub repositories and NVD exploit references (exploit). Absence
here means nothing public was found, not that detection is impossible.
GitHub PoC repositories are collected automatically by
PoC-in-GitHub (opens in a new tab) (CC0) and filtered to repositories that are
still online, contain code, and are starred or at least two weeks old. They are
still not vetted: some are fakes and some are malware. Treat
them as evidence that code was published, not as code to run.
NVD exploit references are links NVD's analysts tag as exploits; they confirm
an exploit was referenced but carry no date. This product uses data from the
NVD but is not endorsed or certified by the NVD.
OpenVAS coverage derives from the Greenbone Community Feed, made available

Metasploit is dated by the first commit of the module file, Exploit-DB by its publication date, and GitHub repositories by their creation date. GitHub PoC repositories are filtered (still online, contain code, starred or at least two weeks old) but not vetted: some are fakes and some are malware, so they show that code was published, not that it works or is safe to run. Evidence tiers are explained on the About page.
CISA Assessment (Vulnrichment / SSVC)
Federal Remediation Window (BOD 26-04)
| If the asset is | Remediate within | Table 1 row |
|---|---|---|
| Publicly exposed | 3 days | 5 of 16 |
| Not publicly exposed | 60 days | 13 of 16 |
BOD 26-04 (opens in a new tab) replaced the single KEV deadline of BOD 22-01 with four inputs: whether the asset is publicly exposed, KEV status, whether exploitation is automatable, and technical impact. Exposure belongs to each agency's asset, not to the CVE, so both outcomes are shown. Automatable and technical impact come from the CISA assessment above. Days are calendar days; for KEV entries the clock starts on the date it was added, and otherwise when the agency identifies the vulnerability on an asset. Agencies make the final exposure call asset by asset, and may set shorter timelines.
