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.

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.

What to do

AI-suggested

To mitigate CVE-2025-70029, organizations should immediately audit their Sunbird-Ed portal configurations to identify any instances where 'rejectUnauthorized' is set to false in HTTP request options. This setting must be changed to true or removed to enforce proper TLS/SSL certificate validation. Developers and administrators should review the codebase and deployment scripts to ensure no insecure overrides disable certificate verification. Implementing strict transport security policies (HSTS) and using certificate pinning where feasible can provide additional layers of defense against MitM attacks. Network-level protections such as enforcing HTTPS-only traffic, using VPNs, and monitoring for suspicious network activity can help reduce exposure. Organizations should also stay alert for official patches or updates from Sunbird-Ed maintainers and apply them promptly once available. Conducting regular security assessments and penetration testing focused on TLS configurations will help detect similar misconfigurations in the future. Training developers on secure coding practices related to TLS usage is recommended to prevent recurrence.

Description

An issue in Sunbird-Ed SunbirdEd-portal v1.13.4 allows attackers to obtain sensitive information. The application disables TLS/SSL certificate validation by setting 'rejectUnauthorized': false in HTTP request options

Impact

The primary impact of CVE-2025-70029 is the compromise of confidentiality due to the ability of attackers to intercept and read sensitive information transmitted over supposedly secure HTTPS connections. This can lead to exposure of user credentials, personal data, educational records, and other confidential information handled by the Sunbird-Ed platform. Since the vulnerability does not affect integrity or availability, attackers cannot modify data or disrupt services directly through this flaw, but the information leakage alone can facilitate further attacks such as account takeover or targeted phishing. Organizations worldwide using Sunbird-Ed for educational management or content delivery face increased risk of data breaches and loss of trust. The ease of exploitation (no authentication or user interaction required) and network-based attack vector mean that attackers on the same network segment or capable of redirecting traffic (e.g., via compromised routers or malicious Wi-Fi hotspots) can exploit this vulnerability. The absence of known exploits in the wild currently reduces immediate risk, but the vulnerability is likely to attract attention from threat actors due to its straightforward exploitation and high impact on confidentiality.
