An issue in Smartcom Bulgaria AD Smartcom Ralink CPE/WiFi router SAM-4G1G-TT-W-VC, SAM-4F1F-TT-W-A1 allows a remote attacker to obtain sensitive information via the Weak default WiFi password generation algorithm in WiFi routers.
Security readout for executives and security teams
Plain-English summary
CVE-2025-22936 concerns Smartcom Ralink CPE/WiFi router models whose default WiFi passwords may be generated predictably. If deployed with default credentials, an attacker could infer the WiFi password and access sensitive network information. The record does not name a patch or confirm active exploitation.
Executive priority
Treat this as a targeted confidentiality risk for affected router deployments, not a confirmed mass-exploitation emergency. Prioritize inventory and credential rotation because the likely fix is operationally simple, while vendor remediation details are not present in the sources.
Technical view
The CVE describes a weak default WiFi password generation algorithm in Smartcom SAM-4G1G-TT-W-VC and SAM-4F1F-TT-W-A1 routers. CVSS 3.1 is 5.7, with adjacent-network attack vector, low complexity, low privileges, no user interaction, and high confidentiality impact only.
Likely exposure
Exposure is most likely where the listed Smartcom router models remain deployed with vendor-generated default WiFi credentials. The CVSS vector indicates adjacent-network reach rather than internet-wide exposure. Asset data in the CVE is incomplete, with vendor/product CPE fields listed as n/a.
Exploitation context
CISA KEV status is false in the provided bundle, and no cited source confirms active exploitation. The public description supports a confidentiality risk from predictable default WiFi credentials, but does not provide evidence of broad exploitation, weaponized tooling, or a vendor patch.
Researcher notes
The CVE record has limited affected-product metadata and no CPE entries. The description names two models and a weak default WPA password generation issue. CVSS uses AV:A and PR:L, which should guide exposure assumptions more than the broad phrase “remote attacker.”
Mitigation direction
Inventory networks for the two named Smartcom router models.
Change default WiFi passwords to strong, unique credentials.
Check Smartcom, ISP, or reseller guidance for firmware or replacement advice.
Prioritize sites using unchanged vendor-generated WiFi credentials.
Document compensating controls where replacement is not immediately possible.
Validation and detection
Confirm whether SAM-4G1G-TT-W-VC or SAM-4F1F-TT-W-A1 devices are deployed.
Verify default WiFi credentials have been changed on identified devices.
Review router labels, procurement records, and wireless SSID inventories.
Check vendor or ISP notices for model-specific remediation guidance.
Look for unexpected WiFi associations or suspicious local network access.

CWE-1391: Exact CWE lookup
Use the exact CWE identifier as the starting point before reviewing related ATT&CK behavior. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
The CVE wording references authentication or credential exposure, so valid-account and credential-access review may help. This is a Glexia inferred lookup path, not an official MITRE, ATT&CK, or CVE Program mapping.
These fields come from the CVE record and ADP containers, not from Glexia's Take. They preserve time-varying source decisions such as CISA SSVC, KEV status, CVSS metrics, and provider references.
We collect every scored CVSS vector available in the official CNA and ADP containers. When more than one version is present, the table keeps the source vectors side by side instead of collapsing them into the highest score.

Use of Weak Credentials
Use of Weak Credentials represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
