Scope: Unchanged
Confidentiality: Low
Integrity: None
Availability: None

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

Attack Vector: Local: The vulnerable component is not bound to the network stack and the attacker’s path is via read/write/execute capabilities. Either: the attacker exploits the vulnerability by accessing the target system locally (e.g., keyboard, console), or remotely (e.g., SSH); or the attacker relies on User Interaction by another person to perform actions required to exploit the vulnerability (e.g., tricking a legitimate user into opening a malicious document).
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: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
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: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

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 2026-10-25.

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 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

1. Monitor Foxit Software announcements closely and apply security patches promptly once available for the affected version 2023.3.0.23028. 2. Until patches are released, restrict the use of Foxit PDF Reader to trusted documents only and educate users about the risks of opening PDFs from unknown or untrusted sources. 3. Employ application whitelisting and sandboxing techniques to limit the ability of Foxit PDF Reader to access sensitive system resources or escalate privileges if exploited. 4. Use endpoint detection and response (EDR) tools to monitor for unusual behavior or memory access patterns indicative of exploitation attempts. 5. Consider deploying network-level protections such as email filtering and web proxy controls to block malicious PDFs and URLs. 6. Review and harden security policies around document handling workflows, especially in high-risk environments. 7. Conduct regular security awareness training emphasizing the dangers of opening unsolicited attachments or links. 8. If possible, use alternative PDF readers with a better security track record until this vulnerability is resolved.

Description

Foxit PDF Reader Annotation Out-Of-Bounds Read Information Disclosure Vulnerability. This vulnerability allows remote attackers to disclose sensitive information on affected installations of Foxit PDF Reader. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the handling of Annotation objects. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the current process. Was ZDI-CAN-22708.

Impact

The primary impact of CVE-2024-30350 is the potential disclosure of sensitive information from the memory space of the Foxit PDF Reader process. This could include data such as user credentials, session tokens, or other confidential information present in memory at the time of exploitation. Although the vulnerability itself does not allow direct code execution or system compromise, it lowers the barrier for attackers to chain this flaw with other vulnerabilities to achieve full system compromise. Organizations relying on Foxit PDF Reader for document handling may face risks of data leakage, especially if users open untrusted PDFs. The requirement for user interaction limits large-scale automated exploitation, but targeted attacks against high-value individuals or organizations remain a concern. The absence of known exploits in the wild reduces immediate risk, but the vulnerability's presence in a widely used PDF reader means it could be weaponized in the future. Overall, the impact is low to moderate depending on the context and presence of other exploitable vulnerabilities.

Base weaknessCWE Top 25 (2025): #8
The product reads data past the end, or before the beginning, of the intended buffer.
Implementation · Input Validation
Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
Architecture and Design · Language Selection
Use a language that provides appropriate memory abstractions.
