EPSS information is unavailable and the vulnerability is not listed in the CISA KEV catalog. Exploitation would require the attacker to have network connectivity to the router, which could be local or remote if the device is exposed. No public exploitation data or known scripts are documented, so the current risk depends on the exposure of the router and the presence of an update to address the issue."}}}}, "created": "2026-03-27T15:47:06.037375+00:00", "title": "Missing Authorization Enables Unauthorized Retrieval and Modification on NEC Aterm Routers", "updated": "2026-03-30T07:02:09.699079+00:00", "vendors": ["nec", "nec$PRODUCT$aterm_w1200ex(-ms)", "nec$PRODUCT$aterm_wf1200cr", "nec$PRODUCT$aterm_wg1200cr", "nec$PRODUCT$aterm_wg1200hp2", "nec$PRODUCT$aterm_wg1200hp3", "nec$PRODUCT$aterm_wg1200hp4", "nec$PRODUCT$aterm_wg1200hs2", "nec$PRODUCT$aterm_wg1200hs3", "nec$PRODUCT$aterm_wg1200hs4", "nec$PRODUCT$aterm_wg1800hp3", "nec$PRODUCT$aterm_wg1800hp4", "nec$PRODUCT$aterm_wg1900hp", "nec$PRODUCT$aterm_wg1900hp2", "nec$PRODUCT$aterm_wg2600hm4", "nec$PRODUCT$aterm_wg2600hp4", "nec$PRODUCT$aterm_wg2600hs", "nec$PRODUCT$aterm_wg2600hs2", "nec$PRODUCT$aterm_wx1500hp", "nec$PRODUCT$aterm_wx3000hp", "nec$PRODUCT$aterm_wx3600hp"]}
