TP-Link Archer C7 (V2)

From Wiki-IoT


Evidence review: 2026-10-21. Overall IDRS grade: not assigned.

All 12 criteria are investigated below. A documented capability, a historical vulnerability and an observed current configuration are different evidence types. Unresolved values are explicitly not scored; absence of a public report is not evidence of absence.

Classification form fields are stored in this page. The evidence table is displayed while required ratings remain unresolved, so no overall grade is assigned. Blank rating choices mean insufficient evidence, not None or Absent.

Assessment scope

Hardware V2, stock firmware. Match country: advisory fix references EU_V2_241108 and US_V2_260427. No cross-region installation assumed; US V2 manual is historical evidence.

No physical device, installed firmware, password, network trace or storage image was inspected. Conditional capability assessments apply only when the named settings are enabled.

Security evaluation

Device

Criterion Finding / rubric choice Evidence and reasoning
Known hardware tampering Physical exposure documented; not rated The V2 guide documents reset, power, Ethernet and USB interfaces. No model-specific physical-resistance test or tampering frequency was verified. Archer C7 US V2 guide
Known vulnerabilities Confirmed vulnerabilities; frequency not quantified The records below establish historical vulnerabilities within the stated firmware scope. They do not measure prevalence or establish a Rare/Very common frequency rating. Archer C7 legacy vulnerability advisory
Prior attacks Not rated: insufficient evidence Vendor cites exploitation reports for this legacy issue, but no C7 V2-specific incident rate. Archer C7 legacy vulnerability advisory
Updatability Rare (CRIS 2; scoped assessment) EOL product with exceptional manually installed patches; no cloud or automatic updates in this advisory scope. Archer C7 legacy vulnerability advisory

System

Criterion Finding / rubric choice Evidence and reasoning
Authentication with other systems Not rated: insufficient evidence Administration authentication exists; all-service and mutual authentication were not established. Archer C7 US V2 guide
Communications Historical HTTP and legacy Wi-Fi options; not rated The V2 manual documents HTTP management and legacy WEP/TKIP as well as WPA2/AES options. A supported secure Wi-Fi option is not proof that every management channel is encrypted. Current patched regional settings were not inspected. Archer C7 US V2 guide
Storage Not rated: insufficient evidence Credential disclosure does not establish whether flash storage itself is encrypted. The methodology refers specifically to device flash, not just user disks, removable media, or encrypted network traffic. Archer C7 legacy vulnerability advisory Archer C7 US V2 guide

User authentication

Criterion Finding / rubric choice Evidence and reasoning
Account management Basic (CRIS 2; scoped assessment) Administrator credentials can be changed; full local role management was not demonstrated. Archer C7 US V2 guide
Authentication Basic (CRIS 2; scoped assessment) Local username/password login is documented; stronger local factors were not established. Archer C7 US V2 guide
Brute-force protection Not rated: insufficient evidence No precise V2/build failed-login lockout policy was verified. Archer C7 US V2 guide
Event logging Partial logging (CRIS 2; scoped assessment) System Log exists; comprehensive access-event auditing is not established. Archer C7 US V2 guide
Passwords Setup-password change documented by staff; not fully rated A TP-Link staff reply for C7 V2 states that newer firmware requires a password at initial setup rather than accepting admin. The old V2 manual describes common defaults. This resolves the historical change in behavior but not mandatory complexity on US_V2_260427 or EU_V2_241108.

Rating calculation

No definitive category score or GRAS is calculated while one or more required CRIS values are unresolved. The method requires taking the ceiling of each complete category mean and summing the three category scores. An unknown must not be substituted with 1 or treated as None. Wiki-IoT methodology

Historical vulnerabilities and remediation

CVE-2023-50224: Improper authentication / credential disclosure

  • Affected scope: Vendor explicitly includes Archer C7 V2/V3; earliest affected builds unspecified.
  • Preconditions: Network-adjacent access to vulnerable httpd.
  • Impact: Sensitive information disclosure, including stored credentials.
  • Remediation: EU V2 241108; US V2 260427. Match region and hardware.
  • Severity: Numeric score not independently verified; omitted.
