Attack Vector: Network
Attack Complexity: Low
Privileges Required: None

Scope: Unchanged
Confidentiality: High
Integrity: None
Availability: None

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: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 4 Jan 2024
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: 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

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 26 Oct 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.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, 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.

AI-suggested

Organizations should immediately audit their use of pbootcms and identify any instances running version 3.1.2. Implementing web application firewalls (WAFs) with rules to detect and block anomalous session behaviors can help mitigate exploitation attempts. Monitoring session management logs for unusual session reuse or access patterns is critical. Additionally, organizations should consider upgrading to a later, patched version of pbootcms once available or migrating to alternative CMS platforms with robust security controls. Enforcing multi-factor authentication (MFA) on backend access points can add an extra layer of defense, although it may not fully prevent session leakage exploitation. Regular security assessments and penetration testing focused on session management controls are recommended to identify similar weaknesses.

Description

Aoyun Technology pbootcms V3.1.2 is vulnerable to Incorrect Access Control, allows remote attackers to gain sensitive information via session leakage allows a user to avoid logging into the backend management platform.

Impact

For European organizations using pbootcms 3.1.2, this vulnerability poses a substantial risk. Unauthorized backend access can lead to exposure of sensitive business data, administrative controls, and potentially customer information stored or managed through the CMS. Attackers could leverage this access to further pivot into internal networks, deploy malicious content, or disrupt business operations. Given that the vulnerability does not affect integrity or availability directly, the immediate risk is data confidentiality breach. However, the backend access could be a stepping stone for more complex attacks. Organizations in sectors with strict data protection regulations such as GDPR may face compliance violations and reputational damage if sensitive information is leaked. The absence of known exploits suggests a window of opportunity for proactive mitigation before widespread exploitation occurs.
