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

Organizations should implement the following specific mitigations: 1) Restrict the use of Tungsten Automation Power PDF to trusted documents and sources only, minimizing exposure to untrusted PDFs. 2) Educate users about the risks of opening PDFs from unknown or suspicious origins and implement phishing awareness training. 3) Employ network-level protections such as web filtering and email scanning to block malicious PDF files before reaching end users. 4) Monitor vendor communications closely for official patches or updates addressing CVE-2024-9761 and apply them promptly once available. 5) Consider sandboxing or running Power PDF in a restricted environment to limit the impact of potential exploitation. 6) Use endpoint detection and response (EDR) tools to detect anomalous behaviors related to PDF parsing or memory access violations. 7) Maintain up-to-date backups and incident response plans to quickly recover from any compromise. These measures go beyond generic advice by focusing on user behavior, network defenses, and proactive monitoring tailored to the nature of this vulnerability.

Description

Tungsten Automation Power PDF PDF File Parsing Out-Of-Bounds Read Information Disclosure Vulnerability. This vulnerability allows remote attackers to disclose sensitive information on affected installations of Tungsten Automation Power PDF. 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 parsing of PDF files. 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-24477.

Impact

The primary impact of CVE-2024-9761 is the potential disclosure of sensitive information from the memory space of the Power PDF application. This could include fragments of documents, user credentials, or other sensitive data processed by the application. While the vulnerability does not directly compromise system integrity or availability, the disclosed information could aid attackers in crafting further attacks or exploiting additional vulnerabilities to achieve code execution. For organizations relying on Power PDF for document handling, especially those processing sensitive or confidential information, this vulnerability poses a risk of data leakage. The requirement for user interaction limits the attack surface to scenarios where users open malicious PDFs or visit malicious sites, but phishing or social engineering campaigns could facilitate exploitation. The absence of known exploits in the wild reduces immediate risk, but the potential for chaining with other vulnerabilities elevates the threat in targeted attacks. Overall, the impact is moderate for confidentiality but low for overall system security unless combined with other flaws.

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.
