Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: None: There is no loss of confidentiality within the impacted component.
Integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 9 Nov 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponized: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 8 Nov 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

Description

CVE-2026-113437 is a path traversal vulnerability in DOS Co., Ltd.'s SS1 and SS1 Cloud products, as well as the ODM product rocoeyes by Rococo Co. Ltd. This flaw allows an attacker to delete arbitrary files by improperly limiting pathname access to restricted directories. The vulnerability has a CVSS 3.0 base score of 5.3, indicating a medium severity level. No public exploits or known active exploitation have been reported. The affected version is specified as version 0. No patch or remediation information is provided.

Impact

An attacker can remotely delete arbitrary files on affected systems without authentication or user interaction, impacting the integrity of the system. There is no impact on confidentiality or availability according to the CVSS vector. No evidence of active exploitation is currently known.

Summary

The vulnerability identified as CVE-2026-113437 involves improper limitation of pathname access in DOS Co., Ltd.'s SS1 and SS1 Cloud products and Rococo Co. Ltd.'s ODM product rocoeyes. This path traversal flaw enables attackers to delete arbitrary files by bypassing directory restrictions. The CVSS 3.0 vector indicates the attack can be performed remotely without privileges or user interaction, impacting integrity but not confidentiality or availability. The vulnerability is published and assigned by JPCERT, with no known exploits in the wild.
