| CVE | Vendor / Product | Sev | Risk | CVSS | EPSS | KEV | Published | Description |
|---|---|---|---|---|---|---|---|---|
| CVE-2023-26451 | Hig | 0.49 | 7.5 | 0.01 | Aug 2, 2023 | Functions with insufficient randomness were used to generate authorization tokens of the integrated oAuth Authorization Service. Authorization codes were predictable for third parties and could be used to intercept and take over the client authorization process. As a result,… | ||
| CVE-2023-26436 | Hig | 0.46 | 7.1 | 0.01 | Jun 20, 2023 | Attackers with access to the "documentconverterws" API were able to inject serialized Java objects, that were not properly checked during deserialization. Access to this API endpoint is restricted to local networks by default. Arbitrary code could be injected that is being… | ||
| CVE-2023-26428 | Med | 0.42 | 6.5 | 0.01 | Jun 20, 2023 | Attackers can successfully request arbitrary snippet IDs, including E-Mail signatures of other users within the same context. Signatures of other users could be read even though they are not explicitly shared. We improved permission handling when requesting snippets that are not… | ||
| CVE-2016-6846 | Med | 0.40 | 6.1 | 0.01 | Mar 29, 2017 | Cross-site scripting (XSS) vulnerability in Open-Xchange (OX) AppSuite backend before 7.6.2-rev59, 7.8.0 before 7.8.0-rev38, 7.8.2 before 7.8.2-rev8; AppSuite frontend before 7.6.2-rev47, 7.8.0 before 7.8.0-rev30, and 7.8.2 before 7.8.2-rev8; Office Web before 7.6.2-rev16, 7.8.0… | ||
| CVE-2023-26443 | Med | 0.36 | 5.5 | 0.01 | Aug 2, 2023 | Full-text autocomplete search allows user-provided SQL syntax to be injected to SQL statements. With existing sanitization in place, this can be abused to trigger benign SQL Exceptions but could potentially be escalated to a malicious SQL injection vulnerability. We now properly… | ||
| CVE-2023-26435 | Med | 0.33 | 5.0 | 0.01 | Jun 20, 2023 | It was possible to call filesystem and network references using the local LibreOffice instance using manipulated ODT documents. Attackers could discover restricted network topology and services as well as including local files with read permissions of the open-xchange system… | ||
| CVE-2023-26431 | Med | 0.33 | 5.0 | 0.01 | Jun 20, 2023 | IPv4-mapped IPv6 addresses did not get recognized as "local" by the code and a connection attempt is made. Attackers with access to user accounts could use this to bypass existing deny-list functionality and trigger requests to restricted network infrastructure to gain insight… | ||
| CVE-2023-26438 | Med | 0.28 | 4.3 | 0.01 | Aug 2, 2023 | External service lookups for a number of protocols were vulnerable to a time-of-check/time-of-use (TOCTOU) weakness, involving the JDK DNS cache. Attackers that were timing DNS cache expiry correctly were able to inject configuration that would bypass existing network… | ||
| CVE-2023-26434 | Med | 0.28 | 4.3 | 0.01 | Jun 20, 2023 | When adding an external mail account, processing of POP3 "capabilities" responses are not limited to plausible sizes. Attacker with access to a rogue POP3 service could trigger requests that lead to excessive resource usage and eventually service unavailability. We now limit… | ||
| CVE-2023-26433 | Med | 0.28 | 4.3 | 0.01 | Jun 20, 2023 | When adding an external mail account, processing of IMAP "capabilities" responses are not limited to plausible sizes. Attacker with access to a rogue IMAP service could trigger requests that lead to excessive resource usage and eventually service unavailability. We now limit… | ||
| CVE-2023-26432 | Med | 0.28 | 4.3 | 0.01 | Jun 20, 2023 | When adding an external mail account, processing of SMTP "capabilities" responses are not limited to plausible sizes. Attacker with access to a rogue SMTP service could trigger requests that lead to excessive resource usage and eventually service unavailability. We now limit… | ||
| CVE-2023-26430 | Low | 0.23 | 3.5 | 0.01 | Aug 2, 2023 | Attackers with access to user accounts can inject arbitrary control characters to SIEVE mail-filter rules. This could be abused to access SIEVE extension that are not allowed by App Suite or to inject rules which would break per-user filter processing, requiring manual cleanup… | ||
| CVE-2023-26429 | Low | 0.23 | 3.5 | 0.01 | Jun 20, 2023 | Control characters were not removed when exporting user feedback content. This allowed attackers to include unexpected content via user feedback and potentially break the exported data structure. We now drop all control characters that are not whitespace character during the… | ||
| CVE-2023-26427 | Low | 0.21 | 3.2 | 0.00 | Jun 20, 2023 | Default permissions for a properties file were too permissive. Local system users could read potentially sensitive information. We updated the default permissions for noreply.properties set during package installation. No publicly available exploits are known. |
